The trick play signal generating means is suitable for generating the first and second trick play signals,

The merging means is suitable for merging the digital information signal and the first or second trick play signal,

The recording means is further characterized in that the reproduction of the reproduction device of the second trick play signal in the fourth reproduction mode and the reproduction of the reproduction of the first trick play signal in the third reproduction mode are performed by the third and fourth reproduction. It is bonded to record the composite signal on a track on the record carrier so that it is enabled at the speed of the substantially same record carrier for both modes.

The present invention is based on the following description. A recording / reproducing apparatus which functions in a so-called STD mode for a known recording apparatus will be described. In this STD mode, the so-called "normal recording mode" and the corresponding "normal play" reproduction mode function at the speed of the recording carrier in both modes such as the first speed v1. The recording apparatus is suitable for generating trick play signals for the various trick play reproduction modes of the STD mode. That is, the corresponding reproducing apparatus can achieve one or more trick play reproducing modes at different recording carrier conveyance speeds, such as the above-described third speed v3 of the trick play reproducing mode, in contrast to the normal play reproducing mode. V3 / v1 = n as described above

An essential feature of the mode trick play signal generated in the trick play playback mode is that such trick play signal is generated at the time of recording, and the trick play signal is recorded in the track on the record carrier in this format, for each trick play speed. 102 sync blocks of trick play data are read by the head during one rotation of the head drum in which the read head is located. In other words, in all trick play reproduction modes, a constant bit rate of the reproduction trick play signal is realized. This is necessary to realize a trick play signal of almost the same picture quality.

The long-term play (LP) record / play mode has a record carrier conveyance speed lower than that of the "normal" record / play mode for the STD v1, i.e., the second speed v2 described above, The rotation speed is the same. Subsequently, the bit transfer rate of the long-term play recording / playback mode drops. In particular, the bit rate is the above-described factor k, which is lower than the bit rate of the "normal" recording / playback mode for the STD; k is equal to or between k = v1 / v2 between the first and second speeds (v1 and v2, respectively). Long-term play recording is described as the second recording mode.

The trick is to pay little attention to trick play in the long play mode. In the trick play reproduction mode of the long term play signal, for example, the trick play signal derived from the long term play signal is reproduced at the fourth speed v4 described above having the aforementioned relationship with the second speed: m v4 / v2. do.

According to the present invention, one or more speeds of one or more trick play playback modes for the LP are selected to be equal to the speed of the trick play playback mode of the STD.

For example, in WO 98-43226 described above, a recording / reproducing apparatus for achieving standard (STD) recording / reproducing is described. Moreover, such an apparatus is suitable for generating trick play signals at three play speeds, which are subsequently merged with a standard mode video signal in a composite signal and recorded on a record carrier. These three trick play speeds are the trick play speed v3 (n =) 4 times the normal play speed v1, the trick play speed 12 times (v1), and the trick play speed 24 times (v1).

Moreover, it is assumed that such a device can achieve an LP mode where k = 3 (the so-called LP3 mode). This means, i.e., the digital video signal, is recorded at a record carrier transport rate such as v1 / 3. Moreover, for the two heads disposed at 180 ° around the head drum and the circumference of the head drum, the video signal is recorded burstwise of each third scan of the head on the record carrier. The trick play mode for LP3 according to the present invention is based on the trick play reproduction speed v4 of 12 times the record carrier speed v2 of the "normal" recording / playback mode of LP3, 36 times of v2 and 72 times of v2. Have. This means that the absolute record carrier transport rates for the two corresponding trick play playback modes (one mode for STD and another mode for LP3) are the same. In other words, in the lowest trick play mode of STD and LP3, the speed is 4v1, the speed is 24v1 in the highest trick play mode of STD and LP, and the speed is 12v1 in the middle trick play mode of STD and LP3.

Another example: The above-described apparatus may realize a second long-term play mode in which k = 5 (so-called LP5 mode). The corresponding trick play playback mode has a record carrier carrying speed equal to 20, 60 and 120 times the record carrier speed of the LP5's "normal" recording / playback mode. Therefore, the trick play mode of the LP5 mode again has the same speed as 4v1, 12v1 and 24v1.

Another example: The above described device can achieve HD mode. In this mode, the record carrier is carried at speed 2v1 or k = 1/2. The HD video signal is recorded by two head pairs disposed at 180 ° near the periphery of the head drum.

At this time, the corresponding trick play reproduction modes are 2 (4 x k), 6 (12 x k), and 12 (24 x k) times of the "normal" recording / reproduction mode of 2v1 HD. Therefore, the trick play mode of HD mode again has the same speed as 4v1, 12v1 and 24v1.

It can be understood that the following relationship exists between the recording data rate (of course, average over time) and the replay data rate.

Record Speed = Replay Speed / n (1)

n is equal to the relative speed ratio between the speed duration replay (playback) and the speed duration record. For example, for the trick play speeds (4x, 12x, 24x) of the normal record carrier speed in the STD mode, n is equal to 4, 12 and 24, respectively. In the corresponding trick play mode of the LP3 mode, n is equal to 12, 36 and 72, respectively.

The replay speed should be kept constant in various modes even in the highest LP mode to maintain sufficient image quality.

Moreover, the following relationship exists between the recording speed of the STD and the recording speed of the LPk mode.

LPk recording speed = STD / k recording speed (2)

The recording speed is determined as the speed at which trick play data as well as normal play data is recorded on the record carrier. Therefore, the recording speed of the trick play data can also be reduced by the k factor of the LPk mode. This may affect the replay speed according to equation (1). In order to prevent the replay speed from decreasing in equation (1), n should be increased by a good factor k. Therefore, this results in the same absolute trick play speed of the various LP modes.

The present invention has the following features.

(a) Overhead is the same for all trick play modes.

(b) The track patterns of the corresponding trick play modes of STD, LP3, LP5 are almost the same,

(c) Generation of trick play signals in various modes may be the same.

(d) In the case of mixed recording with a trick play signal for a corresponding speed (for example, STD following LP3), it is possible to reproduce the trick play signal in the trick play playback mode at the same absolute speed.

(e) Therefore, the scan paths of the heads of the corresponding trick play modes are the same.

Fig. 1 shows the track pattern of the standard STD playback mode at the recording carrier speed of v1 further equipped with the trick play segment of two trick play playback modes at a speed of +12 times and -12 times the normal playback recording carrier speed v1. It is. Figure 1 shows four track groups in this particular example repeated each time. In another example, a track group can include a number of tracks other than 48. The track comprises an information sync block of an information signal, such as a video information signal, as an example encoded in the form of an MPEG encoded information signal. This information signal means reproduction of the standard reproduction mode at the recording carrier speed of v1.

Each track of FIG. 1 contains information of 306 sync blocks that generate 14688 in a total of 48 track groups. The 13344 sync blocks contain normal play data to be described later, and the 1344 sync blocks include trick play data. The normal play data rate is 12.54 Mb / s.

Certain track groups, such as track numbers (2, 4, 6, 8, 15, 17, 19, 21, 26, 28, 30, 32, 39, 41, 43, 45), have reference numbers 10.1 to 10.16. Including the containing segment, wherein the trick play information signal is adjusted. In the example of the present invention, this trick play signal is a trick play signal for enabling the trick play reproduction mode at a record carrier speed of +12 times v1. Incidentally, certain track groups, such as track numbers 44, 42, 40, 38, 33, 31, 29, 27, 20, 18, 16, 14, 9, 7, 5, 3, have reference numerals 12.1 to 12.16), wherein the trick play information signal is adjusted. In the example of the present invention, this trick play signal is a trick play signal for enabling the trick play reproduction mode at a record carrier speed of -12 of v1.

For example, when recording information of 48 track groups by a first recording head having a first azimuth angle and a second head having a second azimuth angle, the reference numeral 14 is assigned. Looking at the slant line in circle 1, the even trick is generated by recording the composite signal with the head of the first azimuth angle, and the even track recording the composite signal with the head of the second azimuth angle. As a result of this, the track is recorded on the record carrier with the next different number (0, 1, 2, 3, ..., etc.). The record carrier speed is v1 of this standard recording mode.

When reproducing information from the 48 track groups by the standard, normal play, playback mode, for example, a first playhead having a first azimuth angle and a second play mode having a second azimuth angle, Looking back at the diagonal line in FIG. 1 with the number 14, the track numbers (0, 1, 2, 3, ..., etc.) are divided by the two tracks and then by another one, i.e. by the first playhead. Even tracks and odd tracks by the second playhead are read. The recording carrier speed is v1 in the standard playback mode. Except for including the normal play information only the trick play segments 10.1 to 10.16, the information in the track is used, and the information including 12.1 to 12.16 is used for reproduction.

During trick play playback at a record carrier speed such as + 12v1, the two playback heads have a first azimuth angle across the record carrier during the first scan (corresponding to half of the head drum rotation in which the head is placed). A second reproduction having a second azimuth angle across the recording carrier during the second scan (corresponding to half of the rotation of the head drum in which the head is disposed), with the scan line of the reproduction head at least almost coinciding with the segments 10.1 to 10.4. The scan line of the head is at least nearly coincident with the segments 10.5 to 10.8, and during the third scan (corresponding to the next half rotation of the head drum on which the head is placed), the first reproduction has a first azimuth angle across the record carrier. The scan line of the head is at least nearly coincident with the segments 10.9 to 10.12, and during the fourth scan (again corresponding to the next half rotation of the head drum in which the head is placed), across the record carrier 1, the scanning line of the second read head having a who asked commerce each scans the record carrier so as to substantially match with the least to segments (10.13 to 10.16).

The trick play segment of the + 12v1 trick play playback mode includes a parity sync block and a plurality of 14 trick play sync blocks each including three times the repetition of the 14 trick play sync blocks. As a result, during each rotation of the head drum, 112 trick play sync blocks are read from the read carrier by the two read heads. In particular, the 112 trick play sync blocks are of course 10 sync blocks including parity information. This is consistent with the example shown in document D1. Since the repetition is again provided to enable accurate retrieval of 112 trick play sync blocks per revolution of the head drum even if there is a tracking error, the scan line described above does not cross the trick play segment in the center of the segment correctly.

In trick play playback at a record carrier speed equal to -12v1, the two playback heads have a first azimuth angle across the record carrier during the first scan (corresponding to half of the head drum rotation in which the head is placed). A scan line of the reproduction head at least substantially coinciding with the segments 12.1 to 12.4, and having a second azimuth angle across the record carrier during the second scan (corresponding to the next half rotation of the head drum in which the head is placed). The scan lines of the two reproduction heads at least substantially coincide with the segments 12.5 to 12.8 and have a first azimuth angle across the record carrier during the third scan (again corresponding to the next half rotation of the head drum in which the head is placed). The scan line of the first reproducing head is at least almost coincident with the segments 12.9 to 12.12, and during the fourth scan (again corresponding to the next half rotation of the head drum in which the head is placed) The recording carrier is scanned such that the scan line of the second reproducing head having the second azimuth angle across the carrier is at least substantially coincident with the segments 12.13 to 12.16.

The trick play segment in the -12v1 trick play playback mode includes a parity sync block and a plurality of 14 play sync blocks, respectively. As a result, during each rotation of the head drum, 112 trick play sync blocks are read from the record carrier by the two read heads. In particular, among the 112 trick play sync blocks, there are 10 trick play sync blocks including parity information. This is consistent with the example shown in document D1. The repetition is provided to enable accurate retrieval of 112 trick play sync blocks per revolution of the head drum even if there is a tracking error, so that the aforementioned scan lines do not cross the trick play segment correctly in the center of the segment.

FIG. 2 shows the track pattern of the LP3 playback mode at the recording carrier speed of v1 / 3 which further includes the trick play segments of two trick play playback modes at +36 times and -36 times the LP3 playback speed of v1 / 3. As shown, this means a reproduction speed of + 12x and -12x of the normal reproduction recording carrier speed v1. Figure 2 again shows the 48 track groups in this particular example repeated every hour.

Again, each track of FIG. 2 contains information of 306 sync blocks that generate 14688 in a total of 48 track groups. The 13344 sync block contains normal play data to be described later, and the 13344 sync block includes trick play data. The normal play data rate is 4.18 Mb / s, which is an expected factor of 3, which is lower than the data rate described above in FIG.

The track contains sync block information of an information signal, such as a video information signal, as in the example encoded in the form of an MPEG encoded information signal. This information signal means reproduction of the LP3 reproduction mode at the recording carrier speed of v 1/3. Furthermore, certain tracks in the group, such as track numbers (2, 4, 6, 8, 15, 17, 19, 21, 26, 28, 30, 32, 39, 41, 43, 45), have a trick play information signal. Up to the segment number 16.1 to 16.16 to be adjusted. In the example of the present invention, this trick play signal is a trick play signal for enabling the trick play reproduction mode at a record carrier speed of +36 times v1 / 3 such as + 12v1. Incidentally, certain tracks in the group, such as track numbers 44, 42, 40, 38, 33, 31, 29, 27, 20, 18, 16, 14, 9, 7, 5, 3, have trick play information. Up to the segment number 18.1 to 18.16 to be adjusted. In the example of the present invention, this trick play signal is a trick play signal for enabling the trick play reproduction mode at a record carrier speed of -36 times v1 / 3 equal to a record carrier speed of 12v1.

For example, when recording information in a group of 48 tracks by the first and second recording heads, the even tracks are generated by recording a composite signal having a head of the first azimuth angle, and the odd tracks are the second edges. Since it is generated by recording the composite signal having the head of the mus-angle, the track is recorded on the record carrier which is of the following other reference numbers (0, 1, 2, 3, ..., etc.). The record carrier speed is v 1/3 of this standard recording mode. To realize this track pattern, during the first rotation of the head drum, the first head records the first track number (0) during the second rotation of the head drum, and the second head tracks during the third rotation of the head drum. The number 1 is recorded, and the information is not recorded at all by both heads. During the fourth rotation, the first head records the track number 2 during the fifth rotation of the head drum, the second head records the track number 3, and during the sixth rotation of the head drum the information is both It is not recorded at all by the head. This recording order is achieved during each subsequent cycle of three revolutions of the head drum.

In the playback of the LP3, the information from the normal play, the playback mode, and the 48 track groups is read in the following manner by the first and second read heads having the first and second azimuth angles, respectively.

During the first rotation of the head drum, the first read head reads the first track number (0) during the second rotation of the head drum, and the second read head reads the track number (1) during the third rotation of the head drum. The information is not read at all by both heads. During the fourth rotation, the first head reads the track number 2 during the fifth rotation of the head drum, the second head reads the track number 2, and during the sixth rotation of the head drum, the information is both It is not read at all by the head. This regeneration sequence is achieved during each subsequent cycle of three revolutions of the head drum. The record carrier speed is v 1/3 in this LP3 playback mode. Only information play information that is information in the track is external information up to the trick play segments 16.1 to 16.16, and 18.1 to 18.16 are used for reproduction.

In trick play playback with a record carrier speed equal to + 12v1 as equal to 36 times the "normal" LP3 speed (v1 / 3), the two read heads are rotated during the first scan (the rotation of the head drum on which the head is placed). The scan line of the first read head having the first azimuth angle across the record carrier at least approximately coincides with the segments 16.1 to 16.4 and during the second scan (of the head drum on which the head is placed). Corresponding to the next half rotation), the scan line of the second playhead with the second azimuth angle across the record carrier is at least approximately coincident with the segments 16.5 to 16.8 and during the third scan (head drum in which the head is placed) Again corresponding to the next half rotation of, the scan line of the first reproducing head having the first azimuth angle across the record carrier is at least approximately coincident with the segments 16.9 to 16.12 and during the fourth scan (head Again corresponds to the next half rotation of the head drum in which is placed), so that the scan line of the second reproducing head having the first azimuth angle across the record carrier is at least approximately coincident with the segments 16.13 to 16.16 .

The trick play segment for this LP3 trick play playback mode includes a plurality of 14 trick play sync blocks, each containing three times the repetition of the parity sync block and the 14 trick play sync blocks. As a result, during each rotation of the head drum, 112 trick play sync blocks are read from the record carrier by the two read heads. In particular, among these 112 trick play sync blocks, there are 10 trick play sync blocks including parity information. This is consistent with the number described above for the trick play playback mode of the STD. Since the repetition is again provided to enable accurate retrieval of 112 trick play sync blocks per revolution of the head drum even if there is a tracking error, the scan line described above does not cross the trick play segment in the center of the segment correctly.

In trick play playback with a record carrier speed equal to -12v1, equal to -36 times the "normal" record carrier speed in LP3 mode (v1 / 3), the two read heads are placed during the first scan Corresponding to half of the rotation of the head drum), the scanning line of the first reproducing head having the first azimuth angle across the recording carrier is at least approximately coincident with the segments 18.1 to 18.4, and during the second scanning (the head Corresponding to the next half rotation of the arranged head drum, the scan line of the second read head with the second azimuth angle across the record carrier is at least nearly coincident with the segments 18.5 to 18.8, during the third scan (head Again corresponds to the next half rotation of the head drum on which the head is placed), the scan line of the first read head having the first azimuth angle across the record carrier is at least approximately coincident with the segments 18.9 to 18.12 , During the fourth scan (again corresponding to the next half rotation of the head drum in which the head is placed), the scan line of the second read head with the first azimuth angle across the record carrier is at least nearly to the segments 18.13 to 18.16. The record carrier is scanned to match.

The trick play segment for this trick play playback mode includes a plurality of 14 trick play sync blocks, each containing three times the repetition of the parity sync block and the 14 trick play sync blocks. As a result, during each rotation of the head drum, 112 trick play sync blocks are read from the record carrier by the two read heads. Among these 112 trick play sync blocks, there are 10 sync blocks including parity information. This is the same as the other trick play playback modes described so far. Since the repetition is again provided to enable accurate retrieval of 112 trick play sync blocks per revolution of the head drum even if there is a tracking error, the scan line described above does not cross the trick play segment in the center of the segment correctly.

FIG. 3 shows the track pattern of an LP5 playback mode at a record carrier speed of v1 / 5 with more trick play segments of two trick play playback modes at +60 times and -60 times the LP5 playback speed of v1 / 5. As shown, this means a reproduction speed of + 12x and -12x of the normal reproduction recording carrier speed v1. Figure 3 again shows the 48 track groups in this particular example repeated every hour.

Again, each track of FIG. 3 contains information of 306 sync blocks that generate 14688 in a total of 48 track groups. The 13344 sync block includes normal play data to be described later, and the 1344 sync block includes trick play data. The normal play data rate is 2.51 Mb / s, which is an expected factor of 5, which is lower than the data rate described above in FIG.

The track contains sync block information of an information signal, such as a video information signal, as in the example encoded in the form of an MPEG encoded information signal. This information signal means reproduction of the LP5 reproduction mode at the recording carrier speed of v1 / 5. Furthermore, certain tracks in the group, such as track numbers (2, 4, 6, 8, 15, 17, 19, 21, 26, 28, 30, 32, 39, 41, 43, 45), have a trick play information signal. Up to the segment number 20.1 to 20.16 to be adjusted. In the example of the present invention, this trick play signal is a trick play signal for enabling the trick play reproduction mode at a record carrier speed of +60 times v1 / 5 such as + 12v1. Incidentally, certain tracks in the group, such as track numbers 44, 42, 40, 38, 33, 31, 29, 27, 20, 18, 16, 14, 9, 7, 5, 3, have trick play information. Up to the segment number 22.1 to 22.16 to be adjusted. In the example of the present invention, this trick play signal is a trick play signal for enabling the trick play reproduction mode at a record carrier speed of -60 times v1 / 5 equal to a record carrier speed of -12v1.

For example, when recording information in a group of 48 tracks by the first and second recording heads, the even tracks are generated by recording a composite signal having a head of the first azimuth angle, and the odd tracks are the second edges. Since it is generated by recording the composite signal having the head of the muscle angle, the track is recorded on the record carrier which is of the following other reference numbers (0, 1, 2, 3, ..., etc.). The record carrier speed is v1 / 5 of this standard recording mode. In order to realize such a track pattern, during the first rotation of the head drum, the first head records the first track number (0). During the second rotation of the head drum, no information is recorded at all by one of the heads. During the third rotation of the head drum, the second head records the track number 1. Information is not recorded on either head on the record carrier during the fourth and fifth rotations of the head drum. During the sixth rotation of the head drum, the first head records the track number 2. During the seventh rotation, information is not recorded in any of the heads of the heads in the recording carrier. During the eighth rotation of the head drum, the second head records the track number 3. This recording order is achieved during each subsequent cycle of five revolutions of the head drum.

In the reproduction of the LP5, the information from the normal play, the reproduction mode, and the 48 track groups is read in the following manner by the first and second read heads having the first and second azimuth angles, respectively.

During the first rotation of the head drum, the first read head reads the first track number (0) during the third rotation of the head drum and the second read head reads the track number (1) during the sixth rotation of the head drum. The first head reads the track number 2 during the eight revolutions of the head drum, and the second head reads the track number 3. This regeneration sequence is achieved during each subsequent cycle of five revolutions of the head drum. The record carrier speed is v1 / 5 in this LP5 playback mode. Only information play information which is information in the track is external information up to the trick play segments 22.1 to 22.16, and 18.1 to 18.16 are used for reproduction.

In trick play playback with a record carrier speed equal to + 12v1 as equal to 60 times the "normal" LP5 speed (v1 / 5), the two read heads are rotated during the first scan (the rotation of the head drum on which the head is placed). The scan line of the first read head having the first azimuth angle across the record carrier at least approximately coincides with the segments 20.1 to 20.4, and during the second scan (of the head drum on which the head is placed). Corresponding to the next half rotation), the scan line of the second reproducing head having the second azimuth angle across the recording carrier at least substantially coincides with the segments 20.5 to 20.8, and during the third scan (head drum in which the head is placed) Again corresponding to the next half rotation of, the scan line of the first reproducing head having the first azimuth angle across the record carrier is at least approximately coincident with the segments 20.9 to 20.12 and during the fourth scan (head Again corresponds to the next half rotation of the head drum on which the recording drum is placed), so that the recording carrier of the second reproduction head having the first azimuth angle across the recording carrier is at least substantially coincident with the segments 20, 13 to 20.16. Inject.

The trick play segment read in this LP3 trick play reproduction mode includes a plurality of 14 trick play sync blocks each containing three times the repetition of the parity sync block and the 14 trick play sync blocks. As a result, during each rotation of the head drum, 112 trick play sync blocks are read from the record carrier by the two read heads. In particular, among these 112 trick play sync blocks, there are 10 trick play sync blocks including parity information. This is consistent with the number described above for the trick play playback mode of the STD. Since the repetition is again provided to enable accurate retrieval of 112 trick play sync blocks per revolution of the head drum even if there is a tracking error, the scan line described above does not cross the trick play segment in the center of the segment correctly.

In trick play playback with a record carrier speed equal to -12v1 since the "normal" record carrier speed in LP5 mode (v1 / 5) is equal to -60 times, the two read heads are placed during the first scan (head placed Corresponding to half of the rotation of the head drum), the scanning line of the first reproducing head having the first azimuth angle across the recording carrier is at least almost coincident with the segments 20.1 to 20.4, and during the second scanning (the head Corresponding to the next half rotation of the head drum disposed), the scan line of the second read head having a second azimuth angle across the record carrier at least approximately coincides with the segments 22.5 to 22.8, during the third scan (head Again corresponds to the next half rotation of the head drum on which the head is placed), the scanning line of the first read head having the first azimuth angle across the record carrier is at least approximately coincident with the segments 22.9 to 22.12. , During the fourth scan (again corresponding to the next half rotation of the head drum on which the head is placed), the scan line of the second read head with the first azimuth angle across the record carrier is at least nearly to the segments 22.13 to 22.16. The record carrier is scanned to match.

The trick play segment for this trick play playback mode includes a plurality of 14 trick play sync blocks, each containing three times the repetition of the parity sync block and the 14 trick play sync blocks. As a result, during each rotation of the head drum, 112 trick play sync blocks are read from the record carrier by the two read heads. In particular, ten of these blocks contain parity information. This is the same as the other trick play playback modes described so far. Since the repetition is again provided to enable accurate retrieval of 112 trick play sync blocks per revolution of the head drum even if there is a tracking error, the scan line described above does not cross the trick play segment in the center of the segment correctly.

4 shows the track pattern of the HP playback mode at the recording carrier speed of 2v1, which is further equipped with two trick play segments of the trick play playback mode at +6 times and -6 times the HP playback speed of 2v1, This means a reproduction speed of + 12x and -12x of the normal reproduction record carrier speed v1. Fig. 4 again shows the 48 track groups in this particular example repeated every time.

Again, each track of FIG. 4 contains information of 306 sync blocks that generate 14688 in a total of 48 track groups. The 13344 sync block contains normal play data to be described later, and the 13344 sync block includes trick play data. The normal play data rate is 25.09Mb / s, which is an expected factor 2, which is higher than the data rate described above in FIG.

The track contains sync block information of an information signal, such as a video information signal, as in the example encoded in the form of an MPEG encoded information signal. This information signal means reproduction of the LP5 reproduction mode at the recording carrier speed of v1 / 5. Furthermore, certain tracks in the group, such as track numbers (2, 4, 6, 8, 14, 16, 18, 20, 26, 28, 30, 32, 39, 41, 43, 45) have a trick play information signal. Up to the segment number 24.1 to 24.16 to be adjusted. In the example of the present invention, this trick play signal is a trick play signal for enabling the trick play reproduction mode at a record carrier speed of +6 times 2v1 such as + 12v1.

In this mode, only (two) heads of the first azimuth angle disposed at 180 ° on the head drum are used to retrieve trick play information from the record carrier.

Incidentally, certain tracks in the group, such as track numbers 45, 43, 41, 39, 33, 31, 29, 27, 21, 19, 17, 13, 9, 7, 5, and 3, have trick play information. Up to the segment number 26.1 to 26.16 to be adjusted. In the example of the present invention, this trick play signal is a trick play signal for enabling the trick play reproduction mode at a record carrier speed of -6 times the recording carrier speed of 2v1 equal to the record carrier speed of -12v1.

In this mode, only (two) heads of the second azimuth angle on the head drum at 180 degrees are used to retrieve trick play information from the record carrier. By recording trick play signals in the forward and reverse directions in the manner described above, this results in the same distribution of trick play data to be recorded over the track. Moreover, this does not cause a problem when arranging trick play information in two directions within a track of the record carrier.

In order to record information in the 48 track groups, the recording apparatus is equipped with two pairs of first and second recording heads disposed at 180 degrees near the periphery of the head drum. The first and second heads of each pair are disposed one side from each other. The first pair of heads records a pair of tracks such as track number (0,1) during half rotation of the head drum. The second pair of heads records the next pair of track numbers (2, 3) during the next half rotation of the head drum. The record carrier speed is 2v1 in this standard recording mode.

In playback with HP, information from the normal play, playback mode, and 48 track groups are read by two pairs of read heads in the same way that tracks are recorded by two pairs of write heads.

During the first half of the first rotation of the head drum, the first pair of read heads is read by the second pair of heads during the second half of the first rotation following the reading of the track number (2,3). The track number (0, 1) is read. This is repeated with each subsequent rotation of the head drum. The recording carrier speed is 2v1 in this HP playback mode. Only normal play information which is information in a track is external information up to trick play segments 24.1 to 24.16, and 26.1 to 26.16 are used for reproduction.

During the first scan (corresponding to the first half rotation of the head drum in which the head is placed), the first read head has at least nearly the scanning line of the first read heads of the first pair of read pairs across the record carrier to the segments 24.1 to 24.4. Coincident, and during the second scan (corresponding to the next half rotation of the head drum in which the head is placed), the write lines of the first read heads of the second pair of ends of the record carrier are at least nearly coincident with the segments 24.5 to 24.8. Inject the carrier. During the next half rotation of the head drum, the first read head of the first pair has at least nearly coincident with the scan lines across the record carrier to the segments 24.9 to 24.12. During the next half rotation of the head drum, the first read head of the second pair scans the record carrier such that the scan lines across the record carrier are at least nearly coincident with the segments 24, 13 to 24.16.

The trick play segment read in this HP trick play playback mode includes three times the repetition of a number of 14 trick play sync blocks and 14 trick play sync blocks, respectively. As a result, during each rotation of the head drum, 112 trick play sync blocks are read from the record carrier by the two read heads. In particular, among these 112 trick play sync blocks, there are 10 trick play sync blocks including parity information. This is consistent with the number described above for the trick play playback mode of the STD. Since the repetition is again provided to enable accurate retrieval of 112 trick play sync blocks per revolution of the head drum even if there is a tracking error, the scan line described above does not cross the trick play segment in the center of the segment correctly.

During trick play playback with a record carrier speed equal to -12v1 as two times the "normal" record carrier speed in HP mode (2v1), the two second readheads of the two pairs of heads (Corresponding to half of the rotation of the first head drum in which the head is placed), the scan carrier is scanned such that the scan line of the second read head of the first pair across the record carrier is at least approximately coincident with the segments 26.1 to 26.4. During the second scan (corresponding to the second half rotation of the first rotation of the head drum in which the head is placed), the scan line of the second read head of the second pair of the second carrier across the record carrier is at least approximately coincident with the segments 26.5 to 26.8. do. During the third scan (which again corresponds to the next half rotation of the head drum in which the head is placed), the scan lines of the second read head of the first pair across the record carrier are at least approximately coincident with the segments 26.9 to 26.12. During the fourth scan (corresponding again to the next half rotation of the head drum in which the head is placed), the scan lines of the second read head of the first pair across the record carrier are at least nearly coincident with the segments 26.13 to 26.16.

The trick play segment for this trick play playback mode comprises a plurality of 14 trick play sync blocks, and three times the repetition of these 14 trick play sync blocks, respectively. As a result, during each rotation of the head drum, 112 trick play sync blocks are read from the record carrier by the two read heads. In particular, ten of these blocks contain parity information. This is the same as the other trick play playback modes described so far. Since the repetition is again provided to enable accurate retrieval of 112 trick play sync blocks per revolution of the head drum even if there is a tracking error, the scan line described above does not cross the trick play segment in the center of the segment correctly.

5, 6, 7 and 8 show the track patterns of STD, LP3, LP5 and HD again. The difference from the track pattern shown in Figs. 1, 2, 3 and 4 is that it includes the track types of Figs. 5, 6, 7 and 8 in addition to "24.k times" of the trick play mode, where k is the STD, Equivalent to 1, 3, 5 and 1/2 of LP3, LP5 and HD modes respectively. Therefore, the track pattern shown in Figs. 5, 6, 7, and 8 may be a pattern obtained by another embodiment of the recording apparatus according to the present invention, or in the apparatus described above with reference to Figs. 1, 2, 3 and 4; It may be a track pattern obtained. In such a case, it should be understood that such a recording device may generate a track pattern including trick play segments of "12.k" times and "24.k" times, but in "24.k" times trick play mode. The trick play segment for is shown in Figures 5, 6, 7, and 8.

FIG. 5 shows a track for the standard STD playback mode at a record carrier speed of v1 further equipped with trick play segments for two trick play playback modes at speeds of +24 times and -24 times normal playback record carrier speed v1. The pattern is shown as in FIG. 5 shows again 48 track groups repeated each time.

Each track in FIG. 5 contains information of 306 sync blocks that generate 14688 in a total of 48 track groups. 1406 sync blocks contain normal play data which will be described later, and 672 sync blocks contain trick play data. The normal play data is 13.18 Mb / s, which is expected to be smaller bits faster than the data rate described above in FIG.

Certain track groups, such as track numbers 6, 8, 10, 12, 14, 16, 18, 27, 29, 31, 33, 35, 37, 39, contain segment numbers 28.1 through 28.14, The trick play information signal is adjusted. In the example of the present invention, this trick play signal is a trick play signal for enabling the trick play reproduction mode at a record carrier speed of +24 times v1. Incidentally, certain track groups such as track numbers 42, 40, 38, 36, 34, 32, 19, 17, 15, 13, 11, 9, 7 include up to segment numbers 12.1-12.16, The trick play information signal is adjusted. In the example of the present invention, this trick play signal is a trick play signal for enabling the trick play reproduction mode at a record carrier speed of -24 of v1.

The method in which the composite signal is recorded on the record carrier to obtain the track shape shown in FIG. 5 is the same as the method described above with reference to FIG.

In addition, the method in which reproduction in the standard, normal play, and reproduction modes occurs is described above with reference to FIG.

During trick play playback at a record carrier speed such as + 24v1, the two playback heads have a first azimuth angle across the record carrier during the first scan (corresponding to half of the head drum rotation in which the head is placed). A second line having a second azimuth angle across the recording carrier during the second scan (corresponding to the next half of the head drum rotation in which the head is placed), with the scan line of the reproduction head at least almost coinciding to the segments 28.1 to 28.7. The scanning lines of the reproduction heads scan the record carriers to at least almost coincide with the segments 28.8 to 28.14.

The trick play segment in the + 24v1 trick play playback mode contains a plurality of eight trick sync blocks and three times the repetition of the eight trick play sync blocks. As a result, during each rotation of the head drum, 112 trick play sync blocks are read from the read carrier by the two read heads. In particular, the 112 trick play sync blocks have 10 sync blocks containing parity information. This is consistent with the example shown in document D1. Since the repetition is again provided to enable accurate retrieval of 112 trick play sync blocks per revolution of the head drum even if there is a tracking error, the scan line described above does not cross the trick play segment in the center of the segment correctly.

In trick play playback at a record carrier speed equal to -24v1, the two playback heads have a first azimuth angle across the record carrier during the first scan (corresponding to half of the head drum rotation in which the head is placed). The scan line of the reproduction head at least substantially coincides with the segments 30.1 to 30.7, and during the second scan (corresponding to the next half rotation of the head drum in which the head is placed), the first having a second azimuth angle across the record carrier. 2 The record carrier is scanned such that the scanning lines of the reproduction heads at least substantially coincide with the segments 30.8 to 30.14.

The trick play segment in the -24v1 trick play playback mode includes three times the repetition of a number of eight trick play sync blocks and eight trick play sync blocks, respectively. As a result, during each rotation of the head drum, 112 trick play sync blocks are read from the record carrier by the two read heads. In particular, among the 112 trick play sync blocks, there are 10 trick play sync blocks including parity information. This is consistent with the example shown in the document D1. The repetition is provided to enable accurate retrieval of 112 trick play sync blocks per revolution of the head drum even if there is a tracking error, so that the aforementioned scan lines do not cross the trick play segment correctly in the center of the segment.

FIG. 6 shows the track pattern of the LP3 playback mode at the recording carrier speed of v1 / 3 having two trick play segments of two trick play playback modes at +72 times and -72 times the LP3 playback speed of v1 / 3. As shown, this means a reproduction speed of + 24x and -24x of the normal reproduction recording carrier speed v1. Fig. 6 again shows the 48 track groups in this particular example repeated every time. Again, each track of FIG. 6 contains information of 306 sync blocks that generate 14688 in a total of 48 track groups. The 14016 sync block includes normal play data to be described later, and the 672 sync block includes trick play data. The normal play data rate is 4.39 Mb / s, which is an expected factor of 3, which is lower than the data rate described above in FIG.

The track contains sync block information of an information signal, such as a video information signal, as in the example encoded in the form of an MPEG encoded information signal. This information signal means reproduction of the LP3 reproduction mode at the recording carrier speed of v 1/3 in the same manner as described above with reference to FIG. Furthermore, certain tracks in the group, such as track numbers 6, 8, 10, 12, 16, 18, 19, 29, 31, 33, 35, 37, 39, 41, are segment numbers to which the trick play information signal is adjusted. (32.1 to 32.14). In the example of the present invention, this trick play signal is a trick play signal for enabling the trick play reproduction mode at a record carrier speed of +72 times v1 / 3 such as + 24v1. Incidentally, certain tracks in the group such as track numbers 42, 40, 38, 36, 34, 32, 30, 19, 17, 15, 13, 11, 9, and 7 are segment numbers to which trick play information is adjusted. (34.1 to 34.14). In the example of the present invention, this trick play signal is a trick play signal for enabling the trick play reproduction mode at a record carrier speed of -72 times v1 / 3 equal to a record carrier speed of 24v1.

The method of recording information in the 48 track groups shown in FIG. 6 is the same as the manner in which the information shown in FIG. 2 is recorded. Therefore, I will not explain any further.

The method of reproducing information in the LP3, normal play, and reproducing modes is the same as the method of reproducing the information shown in FIG. Therefore, the reproduction of this mode will be described as provided in FIG.

In trick play playback with a record carrier speed equal to + 24v1, the two playback heads have a first azimuth angle across the record carrier during the first scan (corresponding to half of the rotation of the head drum in which the head is placed). The scan line of the first reproducing head at least substantially coincides with the segments 28.1 to 28.7, and during the second scan (corresponding to the next half rotation of the head drum in which the head is placed), the second azimuth angle across the recording carrier The record carrier is scanned such that the scanning line of the second reproducing head, which has it, at least nearly coincides with the segments 28.8 to 28.14.

The trick play segment for the + 24v1 trick play playback mode includes three times the repetition of a number of eight trick play sync blocks and eight trick play sync blocks, respectively. As a result, during each rotation of the head drum, 112 trick play sync blocks are read from the record carrier by the two read heads. In particular, among these 112 trick play sync blocks, there are 10 trick play sync blocks including parity information. This is consistent with the example shown in the document D1. Since the repetition is again provided to enable accurate retrieval of 112 trick play sync blocks per revolution of the head drum even if there is a tracking error, the scan line described above does not cross the trick play segment in the center of the segment correctly.

In trick play playback with a record carrier speed equal to -24v1, the two playheads have a first azimuth angle across the record carrier during the first scan (corresponding to half of the rotation of the head drum in which the head is placed). The scan line of the first reproducing head at least substantially coincides with the segments 30.1 to 30.7, and during the second scan (corresponding to the next half rotation of the head drum in which the head is placed), the second azimuth angle across the recording carrier The record carrier is scanned such that the scan line of the second read head it has at least approximately coincides with the segments 30.8 to 30.14.

The trick play segment for the -24v1 trick play playback mode includes three times the repetition of a number of eight trick play sync blocks and eight trick play sync blocks, respectively. As a result, during each rotation of the head drum, 112 trick play sync blocks are read from the record carrier by the two read heads. In particular, among these 112 trick play sync blocks, there are 10 sync blocks including parity information. This is the same as the example shown in the document D1. Since the repetition is again provided to enable accurate retrieval of 112 trick play sync blocks per revolution of the head drum even if there is a tracking error, the scan line described above does not cross the trick play segment in the center of the segment correctly.

FIG. 6 shows the track pattern of the LP3 playback mode at the recording carrier speed of v1 / 3 having two trick play segments of two trick play playback modes at +72 times and -72 times the LP3 playback speed of v1 / 3. As shown, this means a reproduction speed of + 24x and -24x of the normal reproduction recording carrier speed v1. Fig. 6 again shows the 48 track groups in this particular example repeated every time. Again, each track of FIG. 6 contains information of 306 sync blocks that generate 14688 in a total of 48 track groups. The 14016 sync block includes normal play data to be described later, and the 672 sync block includes trick play data. The normal play data rate is 4.39 Mb / s, which is an expected factor of 3, which is lower than the data rate described above in FIG.

The track contains sync block information of an information signal, such as a video information signal, as in the example encoded in the form of an MPEG encoded information signal. This information signal means reproduction of the LP5 reproduction mode at the recording carrier speed of v 1/3. Moreover, certain tracks in the group, such as track numbers 6, 8, 10, 12, 14, 16, 18, 29, 31, 33, 35, 37, 39, 41, are segment numbers to which the trick play information signal is adjusted. (32.1 to 32.14). In the example of the present invention, this trick play signal is a trick play signal for enabling the trick play reproduction mode at a record carrier speed of +72 times v1 / 3 such as + 24v1. Incidentally, certain tracks in the group such as track numbers 42, 40, 38, 36, 34, 32, 30, 19, 17, 15, 13, 11, 9, and 7 are segment numbers to which trick play information is adjusted. (34.1 to 34.14). In the example of the present invention, this trick play signal is a trick play signal for enabling the trick play reproduction mode at a record carrier speed of -72 times v1 / 3 equal to a record carrier speed of -24v1.

The method of recording information in the 48 track groups is the same as the information shown in FIG. 3 is recorded. Therefore, the description of this recording will not be described any further with reference to FIG. 3, but FIG. 3 is for reference.

The method of reproducing the information in the LP5, the normal play, and the reproducing mode is the same as the method of reproducing the information shown in FIG.

In trick play playback with a record carrier speed equal to + 24v1 as equal to 72 times the "normal" LP3 speed (v1 / 3), the two read heads are rotated during the first scan (the rotation of the head drum on which the head is placed). Of the first reproducing head having the first azimuth angle across the recording carrier at least approximately coincides with the segments 32. 1 to 32.7 and during the second scan (of the head drum on which the head is disposed). Corresponding to the next half rotation), the recording carrier is scanned such that the scan line of the second reproducing head having the second azimuth angle across the recording carrier is at least approximately coincident with the segments 32.8 to 32.14.

The trick play segment for this LP3 trick play playback mode includes three times the repetition of a number of eight trick play sync blocks and eight trick play sync blocks, respectively. As a result, during each rotation of the head drum, 112 trick play sync blocks are read from the record carrier by the two read heads. In particular, among these 112 trick play sync blocks, there are 10 trick play sync blocks including parity information. This is consistent with the number described above for the trick play playback mode of the STD. Since the repetition is again provided to enable accurate retrieval of 112 trick play sync blocks per revolution of the head drum even if there is a tracking error, the scan line described above does not cross the trick play segment in the center of the segment correctly.

During trick play playback with a record carrier speed equal to -24v1, equal to -72 times the "normal" record carrier speed in LP3 mode (v1 / 3), the two read heads are placed during the first scan (head placed Corresponding to half of the rotation of the head drum), the scanning line of the first reproducing head having the first azimuth angle across the recording carrier is at least almost coincident with the segments 34.1 to 34.7, and during the second scanning (the head Corresponding to the next half rotation of the arranged head drum), the recording carrier is scanned such that the scan line of the second read head having the second azimuth angle across the recording carrier is at least approximately coincident with the segments 34.8 to 34.14.

The trick play segment for the trick play playback mode includes three times the repetition of a number of eight trick play sync blocks and eight trick play sync blocks, respectively. As a result, during each rotation of the head drum, 112 trick play sync blocks are read from the record carrier by the two read heads. Among these 112 trick play sync blocks, there are 10 sync blocks including parity information. This is the same as the other trick play playback modes described so far. Since the repetition is again provided to enable accurate retrieval of 112 trick play sync blocks per revolution of the head drum even if there is a tracking error, the scan line described above does not cross the trick play segment in the center of the segment correctly.

FIG. 7 shows the track pattern of the LP5 playback mode at the recording carrier speed of v1 / 5, which is further equipped with two trick play segments of the trick play playback mode at +120 times and -120 times the LP5 playback speed of v1 / 5. As shown, this means a reproduction speed of + 24x and -24x of the normal reproduction recording carrier speed v1. FIG. 7 again shows the 48 track groups in this particular example repeated each time. Again, each track of FIG. 7 contains information of 306 sync blocks that generate 14688 in a total of 48 track groups. The 14016 sync block includes normal play data to be described later, and the 672 sync block includes trick play data. The normal play data rate is 2.64 Mb / s, which is an expected factor of 5, which is lower than the data rate described above in FIG.

The track contains sync block information of an information signal, such as a video information signal, as in the example encoded in the form of an MPEG encoded information signal. This information signal means reproduction of the LP5 reproduction mode at the recording carrier speed of v 1/3 as described above with reference to FIG. Moreover, certain tracks in the group, such as track numbers 6, 8, 10, 12, 14, 16, 18, 29, 31, 33, 35, 37, 39, 41, are segment numbers to which the trick play information signal is adjusted. (36.1 to 36.14). In the example of the present invention, this trick play signal is a trick play signal for enabling the trick play reproduction mode at a record carrier speed of +120 times v1 / 5 such as + 24v1. Incidentally, certain tracks in the group such as track numbers 42, 40, 38, 36, 34, 32, 30, 19, 17, 15, 13, 11, 9, and 7 are segment numbers to which trick play information is adjusted. (38.1 to 38.14). In the example of the present invention, this trick play signal is a trick play signal for enabling the trick play reproduction mode at a record carrier speed of -120 times v1 / 5 equal to a record carrier speed of -24v1.

The method of recording information in the 48 track groups is the same as the information shown in Fig. 3 is recorded on the record carrier. Therefore, the description of this recording will no longer be described with reference to FIG. 3, but FIG. 3 is for reference.

The method of reproducing the information in the LP5, the normal play, and the reproducing mode is the same as the method of reproducing the information shown in FIG.

In trick play playback with a record carrier speed equal to + 24v1 since it is equal to 120 times the "normal" LP5 speed (v1 / 5), the two read heads are rotated during the first scan (the rotation of the head drum on which the head is placed). Of the first playhead having the first azimuth angle across the record carrier at least approximately coincides with the segments 36.1 to 36.7, and during the second scan (of the head drum on which the head is disposed). Corresponding to the next half rotation), the recording carrier is scanned such that the scan line of the second reproducing head having the second azimuth angle across the recording carrier is at least approximately coincident with the segments 36.8 to 36.14.

The trick play segment for this LP3 trick play playback mode includes three times the repetition of a number of eight trick play sync blocks and eight trick play sync blocks, respectively. As a result, during each rotation of the head drum, 112 trick play sync blocks are read from the record carrier by the two read heads. In particular, among these 112 trick play sync blocks, there are 10 trick play sync blocks including parity information. This is consistent with the number described above for the trick play playback mode of the STD. Since the repetition is again provided to enable accurate retrieval of 112 trick play sync blocks per revolution of the head drum even if there is a tracking error, the scan line described above does not cross the trick play segment in the center of the segment correctly.

As a result, during each rotation of the head drum, 112 trick play sync blocks are read from the record carrier by the two read heads. In particular, among these 112 trick play sync blocks, there are 10 sync blocks including parity information. This is consistent with the number described above for the trick play playback mode of the STD. The repetition is again provided to enable accurate retrieval of 112 trick play sync blocks per revolution of the head drum, even if there is a tracking error, so the scan line described above does not cross the trick play segment at the center of the segment correctly.
