Description

OPTICAL RECORDING MEANS, METHOD FOR REGISTERING / REPRODUCING THE OPTICAL RECORDING MEDIA AND APPARATUS FOR REGISTERING / REPRODUCING THE OPTICAL RECORDING MEDIA BACKGROUND OF THE INVENTION FIELD OF THE INVENTION This invention relates to an optical recording medium having an oscillating groove, more specifically, the present invention relates to a novel optical recording medium that can record signals with high density. The invention also relates to a method and apparatus for registering and / or reproducing such an optical recording medium. DESCRIPTION OF THE RELATED ART The CD-R disc, used for example in what is known as a compact disc registration system (CD-R), has an oscillating groove. The sector information, including the address information, is recorded by modulating the. oscillating signal. Specifically, in a CD-R recording and / or reproducing apparatus, the oscillating signal having 22 kHz as a carrier wave is detected by means of a registration and / or reproduction light point converging on the groove. A series of data, including address information, is detected by the FM demodulation of the oscillating signal. In a system in which the address is arranged at the front end of the sector, the address information and the registration information are pre-registered by time division, such that the recorded signals become discontinuous signals. With the present system, the data can be continuously recorded, such a feature is meritorious for a request in which the exchange with the read-only disk in which the signals are recorded continuously is emphasized. In a method for recording the address information by modulating the oscillating signal, and the distance between the tracks, which is the distance between the adjacent grooves, is reduced, the leakage of the oscillating signal from the neighboring groove increases, decreasing thus the signal / noise ratio of the oscillating signal. The address information not only can not be demodulated correctly, but the carrier wave of the oscillating signal, required for the rotation control of the disk, becomes difficult to detect thus causing obstructions in terms of the rotation control of the disk. Since it is necessary to reduce the distance between tracks to record the signal with high density, it is necessary to reproduce the address information correctly despite the narrow distance between tracks. Likewise, in the above system, the point of recording and / or reproduction on the disk derived from the reproduced address information depends as to the accuracy of its position of the frequency of the carrier wave and is substantially of the order of the length wave of the carrier wave. On the other hand, the frequency of the carrier wave, which is the oscillating frequency, must be selected at a lower level to avoid negative effects on the registration signal. In the case of CD-R, the oscillation frequency is 22 kHz, with the wavelength on the disk of 54 μm. If the data is recorded discontinuously, ie with interruptions, and the data is subsequently recorded in the registered part, it is necessary to record the data in correct positions on the disk. If a correct record can not be made, what is known as a separation to absorb errors in terms of registration positions between one record data unit and another to avoid splicing between record data must be provided. Since the separations reduce the disk's recording capacity, the length of the separation must be reduced to the maximum. However, the aforementioned accuracy is not enough. SUMMARY OF THE INVENTION Accordingly, it is an object of the present invention to provide an optical recording means wherein the address information and the disk rotation control information can be obtained correctly despite the small distance between tracks to allow the signal Register with high density. Another object of the present invention is to provide a method and an apparatus for recording / reproducing the optical disc. In another aspect, the present invention provides an optical recording means having an oscillating groove and holes formed at a pre-set interval in an area between turns of the oscillating groove. In another aspect, the present invention provides a method for recording and / or reproducing signals in an optical recording medium having an oscillating groove and holes formed at a preset interval in an area between turns of the oscillating groove. The recording method includes controlling the rotation of the optical recording medium by means of an oscillating signal from the groove and detecting the position of the recording medium by pit signals detected from the holes. In another aspect, the present invention provides a recording and / or reproducing apparatus that includes an optical recording medium having an oscillating groove and holes formed at a pre-set interval in an inter-turn area of the oscillating groove, a detection device for detecting a oscillating signal from said groove and /.'''- a detection device for detecting pit signals from the pits, where the rotation of the optical recording medium is controlled by means of the oscillating signals detected from the groove and where the position in the optical recording medium of the registration signal is detected by the hole signal detected from the holes With the above configuration of the present invention, the address information and the rotation information for the optical recording medium can be obtained with precision to despite the narrow distance between tracks thus contributing to a high density recording. The speed of response as well as the reliability of the rotational control of the optical recording medium can also be improved simultaneously. For example, if the CLV disc rotation is controlled alone by means of three surface holes between grooves, these three holes can not be detected temporarily if the linear velocity changes significantly due to random access, so that it takes a considerable time until the redeployment of the pre-holes to resume control of the rotation. This incopveniepte is solved by the use of the oscillating holes and the signals of holes, simultaneously. Furthermore, with the present invention it is possible to derive the address information more accurately and with a - '. time precision greater than is possible with conventional technique. Furthermore, with the optical recording medium of the present invention, if the oscillating signal and the directional signals 5 are read by the single beam, it is possible to detect the read signal corresponding to the reproduction signal, servo signals (signal servo-focusing and servo-tracking signal), oscillating signal and address information in its entirety, thereby simplifying the recording / reproduction apparatus and allowing the recording / reproducing apparatus to be manufactured at reduced costs.

DESCRIPTION OF THE INVENTION An optical recording medium according to the present invention has an oscillating pre-groove and holes formed at pre-established intervals in a defined area between these grooves. The oscillating signal for the groove and the hole signal for the holes are used in combination to allow high density recording. The holes are formed in a defined area between adjacent grooves, that is, on a surface between rows. The pits may be in the form of common pits or may be formed continuously between adjacent pits in the form of cutouts in the surfaces between pits interconnecting the neighboring surfaces between pits. These holes include information on the sector, including incineration pits or management holes, and the address information is obtained through sector information. However, in the present invention, such sector information is not always necessary in such a way that it may be necessary to provide only synchronization holes or steering holes. The synchronization pits indicate the initial position for the sector information and are formed as two holes arranged in close proximity to each other or as pits having pit lengths different from the lengths of the other pits and therefore can be detected as different compared to the remaining holes. On the other hand, a groove may have the oscillating signal of a single frequency or may have the sector information where address data has been recorded by modulation. The sector information is the information related to the sector of the registration data or a group which is a set of sectors of registration data, and includes the synchronization signal and / or the address data. The groove or hole mentioned above can be used in optional combination, that is, for example, the combination of the groove that has the oscillating signal of a single frequency and the hole of synchronization not well hole direction, the combination of the groove that has the signal os-zilante that is demodulated to record information of sector, co or for example synchronization signal or not address data, and the synchronization hole or direction hole, or the combination of the groove having the modulated oscillating signal to record sector information and interval holes pre-established, they can em read resé.

Y} . If, in these ions, the combination of the groove having the single-frequency oscillating signal and the synchronization hole or the dierection hole is used, the synchronization information and the address information 5 can reliably be produced by means of these synchronization holes and steering holes, while the disc rotation control information may be positively produced by the oscillating signal. If the oscillating signal is the signal of a single frequency, Any leakage signal from a neighboring groove is precisely of the same frequency as the frequency of the signal for detection, in such a way that the effect of the leak takes the form of small changes of amplitude in relation to the oscillating signal for detection, and therefore the unique frequency for detection can not be detected easily. If the combination of the groove having the oscillating signal modulated to record the sector information, such as for example synchronization signal or address data, and the synchronization hole or direction hole, the synchronization information is used or the address information is recorded in duplicate in the groove and in the hole, thus ensuring accuracy and reliability. Yes, when the groove and pit are used in combination, the The pit position is randomly formed in relation to the furrow, there is a fear that the resulting reading signal will fluctuate in signal level depending on the pit position to make it more difficult to correctly detect the hole. Also the fear that the circuit 5 for generating clocks in the reproduction apparatus becomes complex in terms of its structure.To overcome this drawback, it is desirable that the relationship between the oscillating frequency fw (medium frequency) and the hole frequency fp be a whole number relationship of as defined by the following equation: M fw = N fp where M and N are integers. Stated differently, the period of oscillation Tw and the period of pit Tp are related to each other by a integer relation between them: M Tw = N Tp where M and N are integers. Meanwhile, the oxidation period Tw is an average oxidation period and the pit period Tp is an interval in which, if the holes are formed at an interval equal to a preset integer multiple of the preset interval, it is equal to said pre-set integer multiple interval. On the other hand, in the case where two consecutive holes are synchronization holes, these two holes are considered as a single hole and the period between these two holes is not taken into consideration to establish the pit period Tp. If the oscillation frequency fw and the pit frequency fp are related to each other by means of a whole number relationship in accordance with the above described, it is possible to unify reference clocks in one or to use a single voltage controlled oscillator, thus simplifying the clock generation circuit of the recording and / or reproducing apparatus. In addition, it becomes possible to generate a signal synchronized with the hole pattern from the oscillating signal by exploiting the PLL, thus establishing the correct detection of the holes. Alternatively, the oscillation phase and the pits phase may correspond to allow a correct detection of pits. That is, by associating the hole position with a pre-set phase of oscillation and by forming a hole in a constant amount of oscillation (fluctuating amount of the groove), the hole detection signal can be stabilized to allow the holes to be Detect correctly. In this case, a pit P can be formed in a center-of-oscillation position of a groove G (a position corresponding to the smallest amount of oscillation), as shown in figure 1. At the same time, the pit P can form in a position close to the neighboring furrow and correspond to the maximum amount of oscillation, as shown in figure 2. In the previous case, parasites from other furrows are minimized, while, in the latter case, it can be detected the hole only by the signal level without removing the oscillating signal component. If the sector information including the synchronization information or the address information is recorded in the oscillating signal, and the holes include the sector information, such as for example the synchronization holes or the address holes, it is desirable that the information The synchronization of the oscillating signals and the sector information, especially the synchronization holes, are in a pre-established positional relationship between them. For example, the synchronization signal by oscillation is recorded within a hole period in front of the synchronization hole in the re-production direction. By previously understanding the position of the pit direction synchronization part from the oscillating signal, more accurate pit direction synchronization can be detected, and as a result the pit direction can be read more reliably . To record / reproduce the above described optical recording medium "'", it controls the rotation of the disc using a signal detected from an oscillating groove, and the position of the registration signal is controlled by means of the information detected from the holes formed on the surface between rows. The recording / reproduction apparatus can be simplified in terms of its structure by reading the oscillating signal and the pit signal simultaneously at the same luminous point using the push-pull method. 10 DESCRIPTION OF THE PREFERRED MODALITIES. With reference to the drawings, the preferred embodiments of the present invention will be explained in detail. FIRST MODALITY An optical disk of the present embodiment is a disk of type of a single writing, 12 cm in diameter, having a recording film of an organic dye in which it can carry out the recording using a laser beam having a wavelength of 635 nm. The disk is formed of polycarbonate and is produced by of injection molding with a guide groove and a surface between turns adjacent to the guide groove. The groove is approximately 0.25 μm wide and approximately 70 nm deep and is formed as a continuous spiral groove from the inner edge to the edge External, and the interval between rows or the distance between tracks is approximately 0.74 μm. The single frequency oscillating signal is recorded as information to control the revolutions per minute of the disc and the clock frequency of the registration signal. The oscillation refers to a slight fructuation of the groove in the radial direction of the disc. In the present embodiment, the fluctuation width is 20 nm and the fluctuation bead is approximately 30 μm. Therefore, if the disk rotates at a linear speed of 3.5 m / sec to reproduce the oscillating signal, the frequency is approximately 120 kHz. On a surface between adjacent turns of the groove, a groove of approximately 0.3 μm in width and approximately 70 n in depth, as a guide groove, is formed as a hole to record the address information (direction hole). With reference to Figure 3, the groove and the steering hole are shown schematically, two steering holes are formed at a pre-established interval in an area between adjacent turns of the groove 1 oscillating guide. The steering holes 2 are formed continuously between turns adjacent to the groove and are formed as grooves extending along the radius of the disk. The steering holes are formed in a range of approximately 0.2 mm in association with 1/0 of the 1¿ > _, , information. That is, there is a direction hole in a position corresponding to the information 1, while there is a direction hole in a position corresponding to the information 0. Therefore, the presence or absence 5 of the direction hole corresponds to 1 / 0 of the information. Figure 4 shows a signal obtained by scanning a light spot B along the groove. Specifically, pulses of a polarity are obtained by the direction holes of the inner edge side and by the holes of direction of the outer edge side of the opposite polarity. It is sufficient if the address information is detected based on one of these two types of impulses. In the present registration system, it can be considered that, if the information occurs successively, the The absence state of the steering holes occurs succisively to make it difficult to detect the steering holes. In the present embodiment, the registration information is previously modulated in a biphasic manner in such a way that the contiguous number is two com maximum.

However, since the out-of-order pattern of 000111 is provided in the synchronization signal to facilitate the detection of the synchronization signal, there is a synchronization signal domain part in which the address or pits are registered for synchronization. three contiguous bits of channel.

Figure 5 shows a modulation effect of data bits and the synchronization pattern. The synchronization pattern is 0110001110001110 and therefore contains three contiguous channel bits of 0 and 1 that are not provided in the modulation rule. The data bits are modulated in such a way that 0 and 1 correspond to 1-0 and 0-1, respectively, so that either contiguous for three or more channel bits are not found in the data part. Figure 6 shows an example of the registration format for the sector information. The sector information consists of a total sum of 208 channel bits, among which the first 16 channel bits represent the synchronization pattern. The 8-byte address data is followed by 4 parity bytes for error correction by the Reed-Solornan code. In the present registration format, since up to 2 bytes can be corrected by the 4 parity bytes, the address data can be detected correctly if 2 optional channel bits of the 208 bit of sector information channel are erroneous. Afterwards, the signal reproduction of the optical disc above ".-. Written. Specifically, the method of simultaneous reading of the oscillating signal of the groove of the direction signal of the holes is explained by a beam.

With reference to Figure 7, which is a block diagram of the signal reproduction circuit, the light returning from the light point B which converges in the groove 1 is converted in a photoelectric manner by means of detectors 5 of PIN-type diode of four segments A, B, C, and D and IV converted to produce signals A, B, C and D corresponding to the respective diodes. Of these signals, the sums of the signals (A + B + B + C) the signal of reading of the recorded signal. The sum signal is compensated for frequency response for recording the reproduction by means of an equalizing circuit 11 and converted into binary signals by means of a binary conversion circuit 12 to produce read signals, from which they produce clocks for the reading data by means of a PLL circuit composed of a phase comparator 13 and a voltage controlled oscillator (VCO) 14. If the calculation of A - B + C + D in the signals A is performed , B, C and D, focus error signals are obtained from the astigmatic system. The focus error signal is sent via the phase co-current circuit 15 to a focus activation circuit 16 from which a focusing activation signal is controlled which controls the focus position 5 of a target lens. . '.. < - If the calculation of A + B - C - D is made in signals A, B, C and D, the track error signals of the push-pull system are obtained. Since this signal is a signal corresponding to the relative position in the radial direction 5 of the groove and of the light point B, the oscillating signal of the groove is reproduced simultaneously. In a position in which a direction hole is formed, a positive impulse or a negative impulse is detected according to whether the direction hole is on the inner edge side or on the outer edge side in relation to the groove. These positive or negative impulses are similarly imcluded in the signal (A + B - C - D). First, this signal (A + B - C - D) passes through a low pass filter (LPF) 17 to only signal track error sent by the phase compensation circuit 18 to a track activation circuit 19 to send the track activation signal. To detect the impulse signals generated by the steering holes, a high-pass filter (HPF) 20 is used. suppresses signals less than 130 kHz to avoid the effect of noise of the low frequency range caused, for example, by fluctuation by oscillation. Since the oscillating signal is a narrow band signal, an oscillating signal with an optimal signal-to-signal ratio The noise can be obtained by using a bandpass filter (GMP) 21 capable of passing the narrow band. The resulting oscillating signal is converted into binary signals by means of a binary conversion circuit 22. The resulting double-level data is compared by means of a frequency comparator circuit 23 with a reference frequency to produce an axis motor control signal. As described above, with the present mode it is possible to produce all the signals required for the signal reproduction using a single 4-segment PIN diode detector. SECOND MODALITY In this modality, several combinations of the oscillating holes are explained. In a first example, the oscillation of a single frequency is explained and holes that have an integer relation in relation to the frequency of the oscillating signal. The signal obtained in this case is as shown in Figure 8, from which it is shown that the pit signals Sp are "detected in a range equal to an integer number of times the period Tw of the oscillating signal Sw, that is to say, at an interval equal to an integer number of times the pit period Tp. In a second example, holes are formed in phase with the modulated oscillating signal. In the first example, the holes are formed in positions close to the adjacent furrow, which corresponds to the maximum oscillation. The pit signals Sp are positioned at the apexes of the swing signal Sw and the holes are detected based only on the signal level of the pit signal S, as shown in figure 9. In figure 9, the pit signal Sp is generated by the hole formed on the inner edge side of the groove during tracking. On the other hand, the pit signal is generated by the hole formed on the outer edge side of the groove. In the first example, the pit signals are detected after the removal of the oscillating signals from the pit signals by a high pass filter. In the present example, the oscillating signal passes through the high pass filter and the holes are detected by the comparison of the pit signal Sp including the oscillating signal with the detection level L. The reason is that, the frequency band of the oscillating signal is close to the frequency band of the pit signals, it can be foreseen that you will find difludes to separate the frequency per meter of the high-pass filter. In the present example, the holes on the inner edge side of the groove are recorded in position corresponding to the maximum oscillation of the groove towards the inner edge. In this case, the outer edge side hole is formed in a maximum oscillation pass towards the inner edge of a furrow adjacent to the outer edge side. The oscillating signal of a given turn of the groove and the oscillating signal of a neighboring turn do not necessarily coincide with each other. Accordingly, if the pit signal Sp from the hole on the inner edge side is positioned at a location corresponding to the constant value of the oscillating signal, the pit signal from the outer edge side hole, registered in association with another When the groove is turned back, an oscillating signal is randomly selected. With reference to Figure 9, the peak values of the pit signals by the hole on the outer edge side, formed in the irrelevant positions for the oscillating signal, vary from hole to hole, while the peak values of the pit signals Sp by the holes of the inner edge side recorded in the constant positions of oscillations, constant aon. If the peak values are constant, the peak values can easily be detected by means of a simple peak retention circuit, in spite of variations in the pit signal amplitudes, so that, by explaining the peak values detected, the hole detection level can be maintained at an optimum level to allow stable hole detection. It is a proper arid of the case in which holes are formed with a substantially constant amount of oscillation.

Moreover, since the pit signals Sp are positioned at the apices of the oscillating signal Sw, the tolerable width of variation of the detection level becomes optimal. This is a merit of the case in which the hole positions correspond to the maximum oscillation and are close to the adjacent furrow. Figure 10 shows an example in which synchronization signals Sws are recorded in the signal oscialnte and are combined with the synchronization pits Ssp. In this case, the positions of the synchronization pits Ssp can be previously known from the synchronization signals Sws of the oscillating signal to ensure a more reliable detection of the synchronization pits Ssp. The following merits are derived from the various combinations described above of the oscillation and the pits. First, the case in which < the oscillation is in phase with the holes. Figure 11 shows a read signal obtained from said optical disk. The reading signal consists of the oscillating signal Sw and the signal of the hole Sp corrupted by the noise components Sn. Figure 12 shows, in a block diagram, a reproduction apparatus for reproducing the oscillating signal and the bean signals. In the present reproduction apparatus, the signal Sw is fed by means of a bandpass filter 31 to a binary conversion circuit 32., while the pit signals Sp are fed by means of a deviation filter 33 to a binary conversion circuit 34, for conversion to respective binary signals. The binary conversion circuit 34 sends the pit signals Sp and the noise components Sn, in accordance with that illustrated in FIG. 11B. The oscillating signal Sw is also sent to a phase comparator 35 for comparing the phase with a signal obtained at a frequency division 1 / M * 100 by a frequency divider 1/100 37 and a frequency divider 1 / M 38 of the oscillation frequency of oscillator 36 controlled with voltage. By controlling the voltage controlled oscillator 36 by the phase information detected by the phase comparator 35, a phase-locked loop is formed, as a result of which a frequency Fo equal to (M * 100) times the frequency Fw of The oscillating signal is emitted by the voltage controlled oscillator 36. If the relationship between the oscillating frequency Fw and the pit frequency is provided by means of Fw * M = Fp / N, the oscillation frequency Fo of the voltage controlled oscillator 36, given by Fo = Fw * (M * 100) = Fp * (N * 100), is equal to (N * 1 0) times the hole frequency Fp. Accordingly, the division by frequency of the voltage oscillator 36 controlled by a meter 39 1 / (N * 100), the phase information presented in FIG. 11C is obtained, and sent to an interpolation circuit 40 and pit momentum detection. Taking the AND of the phase information shown in Fig. 11C and the output of the binary conversion circuit 34, the noise components Sn are canceled, as shown in Fig. 11D, in such a way that the bit data clocks shown in Figure 11E and the bit data presented in Figure 11F are emitted. An example in which the synchronization signals (ion synchronization) are recorded in the oscillating signal and combined with the synchronization holes is explained below. With reference to FIG. 13, an oscillating signal shown in (a) is frequency modulated, and is unbalanced to provide a signal illustrated in (b). Moreover, by arranging the synchronization of the pre-hsyo directly on the back of the oscillation synchronization, as shown in (c), the pre-hole synchronization can be detected after detection of oscillation synchronization . The oscillation itself is as accurate as the pre-holes. However, by providing a pre-hole protection arrangement by means of a system different from the "prehos" system, it is possible to improve the safety of the pre-hole signal itself. As a method of use other than combinational selective switching, a front end of designation signal 5 of a series of pre-holes can be inserted by oscillation, as shown in Figure 14. The result is that there is no need to form the pattern of synchronization by means of the pre-holes thus increasing the accuracy of the pre-holes. Since there is no need By detecting the pre-hole synchronization pattern, circuit savings can be realized. In addition, the control circuit is doubled, thus increasing reliability. Even though the above description has been made based on preferred embodiments of the present invention, it is will note that the present invention is not limited to these simply illustrative embodiments, but may encompass various modifications or combinations. For example, the direction holes 2 can be designed as ordinary holes. 20 If the sector information is recorded both in the oscillating signal and in the holes, these can be used independently of each other. For example, it is possible to exploit the address information by means of the holes before registering the signal and exploiting the information of address registered in the modulated state in the oscillating signal after the signal registration
