DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described in detail with reference to the drawings showing the embodiments. FIG. 1 shows a mini-disc player capable of recording / reproducing a recording / reproducing apparatus according to the present invention.
FIG. 1 is a schematic diagram showing an example of a circuit configuration when implemented as a recording / reproducing MD player.

The control circuit 1 is composed of an MPU (microprocessor), reads out digital data from a drive circuit 2, a mini-disc (hereinafter referred to as MD) 7, and reads / writes digital data into the MD 7. An LCD 5 as a display means, an operation unit 6, a ROM 8, a RAM 9, and the like are connected.

Reference numeral 10 denotes ATRAC (Adaptive Transform A).
coustic Coding) It is an encoder / decoder and ATRAC read from MD7 by read / write circuit 4.
Decodes (decompresses) digital data that has been compressed and encoded by the system, outputs it to the D / A converter 11, and encodes digital data input from the A / D converter 13 into compressed and encoded digital data to read / write circuits. Output to 4. The read / write circuit 4 writes the TOC data, which will be described later, output from the control circuit 1 to the MD 7, reads the TOC data from the MD 7, and provides the control circuit 1 with the TOC data.

The D / A converter 11 converts a digital signal input from the ATRAC encoder / decoder 10 into an analog audio signal and outputs it to an audio output terminal 12. Also, A
The / D converter 13 converts the analog audio signal input from the audio input terminal 14 into a digital signal,
This is given to the decoder 10.

Therefore, if an earphone, a headphone, a speaker, and the like are connected to the audio output terminal 12, it is possible to reproduce and output the data that has been compression-encoded and recorded in the MD 7 as audio, and conversely, the audio input. If a microphone, an audio output terminal of another audio device, or the like is connected to the terminal 14, the voice can be recorded on the MD 7 as compression-encoded data. However, as will be described later, there is a type of MD7 which is exclusively for reproduction, in other words, a type in which data cannot be recorded. In the case of using such an MD7, a voice cannot be recorded.

The MD 7 has a TOC area 7T on the inner side and a data area 7D on the outer side. By the way, the MD 7 has a type capable of recording / reproduction and a type dedicated to reproduction, and both have the same TOC area 7T and data area 7D. In the data area 7D, in principle, audio information such as music is divided into units called tracks (in the case of music information, one music unit) and recorded as digital data by the ATRAC method. Records information about the data recorded in the data area 7D (hereinafter referred to as TOC data), for example, the number of tracks, information specifying each track, a start address and an end address in the data area 7D, and the like. Further, in the case of the reproduction-only type, the name of each track (in the case of music information, the title of the music) is also recorded.

Incidentally, in the MD 7 of the type capable of recording / reproducing, each time the contents of the data area 7D are updated, the TOC area 7T
Is rewritten correspondingly. Needless to say, appropriate means is required to rewrite the contents of the TOC area 7T. However, a read / write circuit 4 is used in a recordable recording / reproducing MD player as means for rewriting the TOC area 7T. It goes without saying that it is used. However, the conventional reproduction-only MD player does not have a means for rewriting the TOC area 7T.

The LCD 5 performs various displays under the control of the control circuit 1. Although details will be described later, the operation unit 6 includes various keys for the user to give various instructions to operate the MD player. The ROM 8 includes software for the “bookmark” function that characterizes the present invention described later.
It stores software for controlling the entire player.
The RAM 9 functions as storage means for temporarily storing various data including the TOC data during the operation of the MD player.

The basic operation of the recording / reproducing MD player as the recording / reproducing apparatus of the present invention is as follows.
When the user instructs reproduction by operating the keys of the operation unit 6,
The control circuit 1 drives the drive circuit 2 to rotate the MD 7. Under the control of the control circuit 1, the read / write circuit 4 first reads TOC data from the rotating TOC area 7T of the MD 7, and reads the read TOC data. Read based on data /
The writing circuit 4 reads digital data obtained by compression-encoding (encoding) an analog audio signal by the ATRAC method from the data area 7D, and reads the digital data from the ATRAC encoder / decoder 10
Give to. The digital data read from the data area 7D is decompressed (decoded) by the ATRAC encoder / decoder 10, converted into an analog audio signal by the D / A converter 11, and output to the audio output terminal 12.

On the other hand, when the MD 7 is a recordable type, recording of an audio signal is possible. Audio input terminal
When an analog audio signal is input to 14, it is converted into a digital signal by the A / D converter 13 and input to the ATRAC encoder / decoder 10. The ATRAC encoder / decoder 10 compresses and encodes the input digital signal and supplies it to the read / write circuit 4. The read / write circuit 4 converts the digital data compressed and encoded into the data area 7D of the MD 7 under the control of the control circuit 1. Record.

When the recorded contents of the data area 7D of the MD 7 are updated, for example, when data is newly recorded or deleted, the control circuit 1 generates TOC data. Instead of being written to the area 7T, it is temporarily stored in the RAM 9. At an appropriate timing, for example, when the MD 7 is ejected from the apparatus, or when the power of the apparatus is turned off, the control circuit 1 reads / writes the data.
By controlling the writing circuit 4 from the RAM 9 to the TOC area 7T of the MD 7
Write TOC data.

FIG. 2 is a schematic diagram showing an example of a circuit configuration when the reproducing apparatus according to the present invention is realized as a reproduction-only mini-disc player (hereinafter referred to as a reproduction-only MD player). The difference from the recording / reproducing MD player shown in FIG. 1 is that the A / D converter 13 and the audio input terminal 14 are not provided, and the ATRAC encoder / decoder 10 has the ATR
In the AC decoder 10R, the read / write circuit 4 is replaced with a read circuit 4R, respectively, and the TOC write circuit 3 is further provided. Other components are common, except that, for example, the control circuit 1 does not have a function relating to recording, and the operation unit 6 also has no function relating to recording.

As described above, the conventional reproduction-only MD player has no means for rewriting the TOC area 7T, but the reproduction-only MD player as the reproduction apparatus of the present invention has the TOC writing circuit 3 described above. It is possible to rewrite the recordable TOC area 7T of the MD 7 as necessary.

The basic operation of such a reproduction-only MD player as the reproduction apparatus of the present invention is as follows. When a user operates a key of the operation unit 6 to instruct reproduction, the control circuit 1 drives the drive circuit 2 to rotate the MD 7, and the control of the control circuit 1 causes the read circuit 4 R to rotate the MD 7.
First, the TOC data is read from the TOC area 7T, and based on the read TOC data, the readout circuit 4R reads the digital data obtained by compressing and encoding the analog audio signal from the data area 7D by the ATRAC method.
Give to ATRAC decoder 10. The digital data read from the data area 7D is expanded (decoded) by the ATRAC decoder 10, converted into an analog audio signal by the D / A converter 11, and output to the audio output terminal 12.

As described above, the reproduction-only MD player as the reproduction apparatus of the present invention has the TOC writing circuit 3, so that the TOC area 7T of the recordable MD 7 is stored in the TOC area 7T.
Although data can be recorded, when the TOC data is generated by the control circuit 1, the data is not immediately written to the TOC area 7T but is temporarily stored in the RAM 9. At an appropriate timing, for example, when the MD 7 is ejected from the device or when the power of the device is turned off, the control circuit 1 controls the TOC writing circuit 3 to read the TOC of the MD 7 from the RAM 9.
Write TOC data to area 7T.

FIG. 3 is a schematic diagram showing the key arrangement of the operation unit 6 of the recording / reproducing MD player whose configuration example is shown in FIG. 1, and FIG. 4 is a reproduction whose configuration example is shown in FIG. Dedicated MD
FIG. 4 is a schematic diagram showing a key arrangement of an operation unit 6 of the player. The difference between the two is that the recording / reproducing MD player shown in FIG. 3 instructs the recording (recording of the audio signal data to the MD 7) “RE.

The "Bookmark" has a "No./NAME" key 71.
It is also possible for the user to give an arbitrary number or name by the operation of.

FIG. 5 is a flowchart showing a processing procedure by the control circuit 1 when a bookmark-related key is operated.

First, the control circuit 1 controls the read circuit 4R to read the contents of the TOC area 7T of the MD 7, and obtains information on all bookmarks already set, for example, addresses,
The type and the like are temporarily stored in the RAM 9 (step S11).

Next, it is checked whether or not the MD7 is being reproduced.
(Step S12) If it is during playback, it is checked whether or not the bookmark related keys 70, 71, 72, 73, 74 have been operated (Step S13), and if those keys have been operated, The process is executed (Step S14). Then, the control circuit 1 checks whether the "power" key 90 or the "EJECT" key 94 has been operated (step S15). If either key has been operated, the control circuit 1 is currently used. It is checked whether or not the MD 7 is a recordable type (step S16). If it is a recordable type, the TOC writing circuit 3 is controlled to
The bookmark-related information stored in M9 is stored in the TOC area 7T of MD7.
(Step S17), and the power is turned off or the MD 7 is ejected (step S18).

If the MD 7 is not being reproduced in step S12, the control circuit 1 executes another process and returns to step S12 (step S19). Step S1
If neither the "power" key 90 nor the "EJECT" key 94 is operated in step 5, the control circuit 1 returns the process to step S12. Further, if it is determined in step S16 that the MD 7 is for reproduction only, the control circuit 1 proceeds to step S18 as it is, so that the information on the bookmark stored in the RAM 9 is deleted. However, as long as the power is not turned off and the MD 7 is not ejected, the information on the bookmark set for the MD 7 stored in the RAM 9 is not deleted. You can set and use bookmarks.

FIG. 6 is a flowchart showing a processing procedure by the control circuit 1 when the "bookmark" key 70 is operated.

When the "bookmark" key 70 is operated, the control circuit 1 stores the address of the data area 7D being reproduced at that time in the RAM 9 as a "bookmark" position (step S21). It is determined whether or not the "NAME" key 71 has been operated (step S22). When the "No./NAME" key 71 is operated, the control circuit 1 stores the input number or name in the RAM 9 in association with the previously stored "bookmark" position (step S23).

FIG. 7 is a flowchart showing a processing procedure by the control circuit 1 when the "END" key 72 is operated.

When the "END" key 72 is operated, the control circuit 1 sets the address of the data area 7D being reproduced at that time to "E".
It is stored in the RAM 9 as the "ND bookmark" position (step S31), and it is checked whether or not the "bookmark" is set at an address before that (step S32). If “bookmark” is not set in the previous address, the control circuit 1 displays a message prompting the user whether to set “bookmark” in the top address of the data area 7D on the LCD 5 and selects the user. Then, when the user instructs the setting, the start address of the data area 7D is stored in the RAM 9 as the “bookmark” position (step S34).

FIG. 8 is a flowchart showing a processing procedure by the control circuit 1 when the "JUMP" key 73 is operated.

When the "JUMP" key 73 is operated, the control circuit 1 sets the address of the data area 7D currently being reproduced to "JUP".
It is stored in the RAM 9 as the "MP bookmark" position (step S41), and it is checked whether or not the "bookmark" is set in the subsequent addresses (step S42). If "bookmark" has already been set in the subsequent addresses, the control circuit 1 stores the "bookmark" position in the RAM 9 also as an "END bookmark" position (step S43).

On the other hand, if "bookmark" is not set in the subsequent addresses, the control circuit 1 displays a message prompting the user to set "bookmark" on the LCD 5 (step S4).
4), wait until the user operates the "bookmark" key 70
(Step S45). When the user operates the "bookmark" key 70 at any time after operating the "JUMP" key 73, the control circuit 1 stores the address of the data area 7D at that time in the RAM 9 as the "END bookmark" position (step S46).

FIG. 9 is a flowchart showing a processing procedure by the control circuit 1 when the "DEL." Key 74 is operated.

When the "DEL." Key 74 is operated, the control circuit 1 sets the address of the data area 7D being reproduced at that time to "DEL."
The L. bookmark position is stored in the RAM 9 (step S51), and it is checked whether the currently reproduced MD 7 is of a reproduction-only type or is write-protected (step S52).
If the MD 7 being reproduced is of a reproduction-only type or is write-protected (YES), the control circuit 1 outputs "DEL."
The operation of the key 74 is ignored, and the “bookmark” position is also stored in the RAM 9 as the “END bookmark” position (step S54).

However, if the MD 7 being reproduced is a reproduction-only type or is not write-protected (NO),
Next, the control circuit 1 checks whether or not a “bookmark” is set in the subsequent addresses (step S53). If “bookmark” has already been set in the subsequent addresses, the process proceeds to step S54.

On the other hand, when the “bookmark” is not set in the subsequent addresses (NO), the control circuit 1 displays a message prompting the user to set the “bookmark” on the LCD 5 (step S55). It waits until the "bookmark" key 70 is operated (step S56). When the user operates the "bookmark" key 70 at any time after operating the "JUMP" key 73, the control circuit 1 stores the address of the data area 7D at that time in the RAM 9 as the "END bookmark" position (step S57).

As described above, a bookmark can be set in the reproduction-only MD player as the reproducing apparatus of the present invention. However, the operation using the bookmark set as described above (hereinafter, the bookmark operation and the bookmark operation) will be described. ) Will be described with reference to the flowcharts of FIG.

FIG. 10 is a flowchart showing a processing procedure by the control circuit 1 of the bookmark scan function which is executed when the "SCAN" key 81 is operated after the "bookmark operation" key 80 is operated.

When the "SCAN" key 81 is operated (step
S61), first, the control circuit 1 displays a message prompting the user to select a bookmark type on the LCD 5 (step S62). When the user selects any type of bookmark by operating the “Execute” key 93 or the like in response to this message (step S6).
3) Next, the control circuit 1 displays a message prompting the user to select a sorting method (step S64). In response to this message, the user selects one of the sorting methods by operating the "Execute" key 93 or the like (step S65), and clicks "Play".
When the key 62 is operated (step S66), the control circuit 1 sequentially reads the addresses of the selected type of bookmark from the RAM 9 according to the selected sorting method (step S67).
The data in the data area 7D of the MD 7 is read from the address and reproduction is started (step S68).

The above-mentioned sorting method can be performed, for example, in the case where a number is assigned to a selected type of bookmark, in ascending or descending order, or random selection. When a name is given to a bookmark, it can be selected in ascending or descending alphabetical order or alphabetical order, or can be randomly selected.

When a predetermined time, for example, 10 seconds has elapsed (step S69), the control circuit 1 checks whether or not the above-described processing has been completed for all the bookmarks of the specified type.
(Step S70) If not finished, step S67
The process is returned to and the address of the next specified type of bookmark is read.

When the processing has been completed for all the bookmarks of the designated type, the control circuit 1 terminates this processing. Even before that, the user forcibly terminates the operation by operating the "stop" key 65 or the like. Of course it is possible.

In the bookmark scanning function by operating the "SCAN" key 81 as described above, bookmarks of the type selected by the user are sequentially sorted by a predetermined time (for example, 10 seconds) at the beginning of the bookmark in the sorting method selected by the user. Will be regenerated.

FIG. 11 is a flowchart showing a processing procedure by the control circuit 1 of the bookmark repeat function which is executed when the "REPEAT" key 82 is operated.

After the “bookmark operation” key 80 is operated, “

In response to this message, the user selects one of the bookmarks by operating the "Execute" key 93 or the like (step S83), and operates the "play" key 62 (step S84), and the control circuit 1 displays the selected bookmark. The address is read from the RAM 9 (step S85), the data in the data area 7D of the MD 7 is read from the address, and reproduction is started (step S86).

When the reproduction address reaches the next bookmark position or the end address of the track (step S87),
The control circuit 1 temporarily stops the reproduction (step S88), and again displays on the LCD 5 a message prompting the user to select a bookmark.
(Step S89), a state of waiting for key input is entered (Steps S130, S131, S132). If the user selects another bookmark ("YES" in step S130), the control circuit 1 returns to step S84. Therefore, if the "play" key 62 is operated at this point, the playback is restarted from the bookmark selected by the user in step S130. Step S8
In the state where a message prompting to select a bookmark is displayed in step 9, the user does not select a new bookmark and
If the key 62 has been operated ("YES" in step S131), the control circuit 1 returns the process to step S86, and first proceeds to step S8.
The bookmark selected in step 3 becomes valid again, and playback resumes from the same bookmark (repeat playback). Furthermore, if the user operates the "stop" key 65 without selecting a new bookmark while a message prompting the selection of a bookmark is displayed in step S89 ("YE" in step S132)
S "), the control circuit 1 terminates the processing. However, even before that, the user can forcibly terminate the processing by operating the" stop "key 65 or the like.

In the bookmark repeat function by operating the "REPEAT" key 82 as described above, reproduction from one bookmark selected by the user to the next bookmark position or the end position of the track is performed.

FIG. 12 is a flowchart showing a processing procedure by the control circuit 1 of the bookmark editing function executed when the "EDIT" key 83 is operated.

When the "EDIT" key 83 is operated after the "bookmark operation" key 80 is operated (step S91), the control circuit 1 first selects whether to replace or delete the bookmark on the LCD 5. A message prompting the user is displayed (step S92). When the user selects the replacement for this message (step S93), the following processing is performed.

First, the control circuit 1 displays on the LCD 5 a unique number of a bookmark stored in the RAM 9, for example, a number automatically assigned in the order of setting (step S9).
Four). In this state, when the user operates the “numeric” key 92 or the like to newly assign a number (step S95), and instructs the replacement with the “execute” key 93 or the like (step S96), the control circuit 1
Stores the replaced number in the RAM 9 (step S97), and ends this processing.

On the other hand, if the user selects deletion in step S93, and the user instructs execution of the deletion by operating the “execute” key 93 or the like (step S101), the control circuit 1 reads “DEL. Is sequentially read out (step S102), and the data in the data area 7D of the MD 7 between these addresses is deleted (step S103). When the above process is completed for all "DEL. Bookmarks" (step
(S104), the control circuit 1 ends this processing.

In the bookmark editing function by operating the "EDIT" key 83 as described above, a bookmark can be set by a user-assigned number, and a user of the data area 7D of the MD 7 is determined to be unnecessary. The set "DE
Deletion of data between "L. Bookmark" and "END Bookmark" is easily performed.

FIG. 13 is a flowchart showing a processing procedure by the control circuit 1 of the bookmark deleting function executed when the "bookmark DEL." Key 85 is operated.

After the “bookmark operation” key 80 is operated,
When the "Bookmark DEL." Key 85 is operated (step S111),
First, the control circuit 1 displays a message prompting the user to select whether to delete individual bookmarks or all bookmarks on the LCD 5 (step S112). When the user selects individual deletion by operating the "Execute" key 93 or the like in response to this message (step S113), the following processing is performed.

First, the control circuit 1 displays a message prompting the user to select a bookmark on the LCD 5 (step S114). For example, when the user selects one bookmark by operating the "Execute" key 93 or the like (step S115) and then operates the "bookmark DEL." Key 85 (step S116), the control circuit 1 determines whether the bookmark has been selected by the user. Erase information from RAM9
(Step S117).

On the other hand, in step S113, the "execute" key
If the user selects all bookmarks to be deleted by operating 93 or the like, and the user next operates the “bookmark DEL.” Key 85 (step S121), the control circuit 1 will delete all bookmarks stored in the RAM 9 Erase information (Step S12
2)

In the bookmark erasing function by operating the “bookmark DEL.” Key 85 as described above, one bookmark selected by the user or all bookmarks already set are erased collectively.

The "ADJUST" key 84 is a key for finely adjusting the bookmark position. The operation is basically the same as the operation for dividing a track of a normal mini-disc player, and therefore, is omitted. I do.

In the above-described embodiment, the present invention is applied to a reproduction-only mini-disc player as a reproducing apparatus in which the configuration example is shown in FIG. 2 and the key arrangement of the operation section 6 is shown in FIG. I explained the case where
In a recording / reproducing mini-disc player as a recording / reproducing apparatus whose configuration example is shown in FIG. 1 and the key arrangement of its operation unit 6 is shown in FIG. 3, a read / write circuit 4 is used instead of the TOC write circuit 3. But ATRAC decoder 10R
Instead, the ATRAC encoder / decoder 10 operates. Therefore, in the recording / reproducing mini-disc player as a recording / reproducing device, it is needless to say that the TOC data writing circuit 3 does not need to be separately provided since the originally provided reading / writing circuit 4 writes the TOC data.

The present invention is not limited to the above-described mini-disc player, but also includes an area in which a user can arbitrarily write data or an area corresponding to a data area 7D in which data is written in advance, and an area corresponding to the area. Data is recorded on a disk medium, such as a CD, DVD, etc., having an area corresponding to the previously recorded TOC area 7T or capable of recording management information for managing the recorded data, and It is needless to say that the present invention can be applied to various devices capable of recording data on a recording medium such as a RAM card, a RAM chip, and the like, and further reproducing data. .

[0079]

As described in detail above, according to the recording / reproducing apparatus of the present invention, it is possible to set a bookmark at an arbitrary position in the data in the data area by providing a so-called "bookmark" function. Therefore, operability and functionality are improved. If a recording medium that can not only reproduce data but also record data is used, the bookmark information is stored in the recording medium even after the recording medium is ejected from the device or after the device is turned off. Is done. When a recording medium that can only reproduce data is used, setting a bookmark and setting a bookmark are not performed unless the recording medium is ejected from the apparatus and the power of the apparatus is not turned off. It is also possible to store the information in the device.

Further, according to the reproducing apparatus of the present invention, by providing a so-called "bookmark" function, it becomes possible to set a bookmark at an arbitrary position of the data in the data area. Is improved. When a recording medium capable of not only reproducing data but also recording data is used, even after the recording medium is discharged from the apparatus or the apparatus is turned off, the apparatus is a reproduction-only apparatus. Later, information about the bookmark is stored on the recording medium.
When a recording medium that can only reproduce data is used, setting a bookmark and setting a bookmark are not performed unless the recording medium is ejected from the apparatus and the power of the apparatus is not turned off. It is also possible to store the information in the device.
