TECHNICAL FIELD OF THE INVENTION
The present invention relates to an optical disk such as a CD-ROM disk, a CD-R / RW disk, a CD + R / RW disk, a DVD-R / RW disk, a DVD + R / RW disk, a magneto-optical disk such as an MO disk, a hard disk, a flexible disk, and an LS120. Recording / reproducing apparatus for recording / reproducing data on / from a recording medium such as a magnetic disk such as a hard disk, a ZIP, etc., a nonvolatile RAM, a ROM, etc., an information recording / reproducing method, a program and a computer readable recording the program It relates to a recording medium.
[0002]
[Prior art]
As computers and digital devices have become indispensable for business and daily life, recording media (information recording media) have become more logical, such as physical compatibility of data, file systems and application formats. For example, importance has been placed on such aspects as compatibility, the same (original) properties of media, the ability to be used physically for a long period of time and the longevity of storing recorded data for a long period of time, and the accuracy of recorded data. In particular, magnetic recording media and optical recording media are easy to handle and the tendency is remarkable.
[0003]
When using such a digitally recordable recording medium, the recording unit and the reproduction unit are considerably different depending on the circumstances of each recording device, reproduction-only device, and recording medium. For example, in the case of a CD-R disc, a recording method which was initially only a disc-at-once method (a method of writing all at once from the beginning to the end) was subdivided into sessions, tracks, and packets in several stages. Further, there are cases where recording and reproduction can be performed in units of sectors like a hard disk, but recording may be performed only in units of clusters depending on the OS or application.
Therefore, conventionally, an information recording apparatus that records and reproduces data so that a recording unit and a reproduction unit are different from each other on a recording medium (for example, see JP-A-2000-278645 and JP-A-06-28778) is used.
[0004]
[Problems to be solved by the invention]
However, in the conventional information recording / reproducing apparatus, since the total recording amount recorded on the recording medium is fixed to an integral multiple of the recording unit, when data recording on the recording medium is completed, recording is instructed from the host computer. The actual data amount of the recording data differs from the actual recording amount at which the recording operation was actually performed.
Such a situation often occurs in an information recording / reproducing apparatus, when a recording command less than a recording unit is issued, waits until the next command comes until the recording unit is satisfied, or forcibly. When the command (Sync) or the medium ejection command (Eject) that satisfies the recording unit is received, the portion that is not enough is filled with the specific pattern data by the apparatus itself (in most cases, it is called zero padding because it is zero). Because it is recorded.
[0005]
FIG. 8 is an explanatory diagram showing that the actual data amount of the recording data is different from the actual recording amount at which the recording operation is actually performed.
Here, a recording medium having a total recording amount of 40 sectors in which a recording unit is 10 sectors and a reproduction unit is 1 sector is used. The address is 0-39.
The figure shows the recording from the unrecorded state (BLANK) shown in (a) of the figure to the middle of the state shown in (b) of the figure, and the additional writing stage shown in (c) of the figure. I have.
As shown in FIG. 2A, recording is performed by a recording command and data transfer of 25 sectors, but recording of 30 sectors is actually performed due to the limitation of the information recording / reproducing apparatus. Therefore, as shown in FIG. 3B, recording of 5 sectors is performed, but recording from 30 sectors must be instructed. Further, as shown in FIG. 3C, in order to perform recording of 5 sectors even in recording from 30 sectors, all remaining 10 sectors must be recorded.
[0006]
Therefore, the conventional information recording / reproducing apparatus has a problem that the total recording amount of data recorded on a recording medium is different from the recording amount by a recording operation instructed from a host computer or the like.
SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and is intended to make the total recording amount of data recorded on a recording medium equal to the recording amount by a recording operation instructed from a host computer or the like. With the goal.

[0012]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, embodiments of the present invention will be specifically described with reference to the drawings.
FIG. 1 is a block diagram showing a configuration of an optical disk device according to an embodiment of the present invention. The arrows in the figure indicate the directions in which data mainly flows, and for simplification of the figure, the CPU 18 that controls each block is described only with a thick line with an arrow to connect to each block. Omitted.
[0013]
This optical disk device is an information recording / reproducing device such as a CD-R / RW drive for recording and reproducing data on and from a recording medium on an optical disk 1 such as a CD-R / RW disk so that the recording unit and the reproduction unit are different. Motor 2, optical pickup 3, laser control circuit 4, CD encoder 5, CD-ROM encoder 6, ATIP decoder 7, buffer RAM 8, buffer manager 9, read amplifier 10, CD decoder 11, CD-ROM decoder 12, ATAPI / SCSI An interface (I / F) 13, a motor driver 14, a servo unit 15, a D / A converter 16, a ROM 17, a CPU 18, and a RAM 19 (including a nonvolatile RAM).
[0014]
The CPU 18 controls the operation of the entire apparatus by using the RAM 19 according to programs and data on the ROM 17 (or the RAM 19), and also realizes various functions according to the present invention. This optical disk device relates to a writable and rewritable CD, but the configuration is almost the same for DVD-type disks, and can be dealt with by expanding their respective functions.
The ROM 17 stores a program described in a code decodable by the CPU 18.
When the power is turned on, the program is loaded into a main memory in the CPU 18 (not shown), and the CPU 18 controls the operation of each unit according to the program, and temporarily stores data and the like necessary for control in the RAM 19. To save.
[0015]
In this optical disk device, an optical disk 1 is driven to rotate by a spindle motor 2. The spindle motor 2 is controlled by a motor driver 14 and a servo unit 15 so that the linear velocity becomes constant. The linear velocity can be changed stepwise.
The optical pickup 3 incorporates a well-known semiconductor laser (light source), an optical system, a focus actuator, a track actuator, a light receiving element, and a position sensor, not shown, and irradiates the recording surface of the optical disc 1 with laser light LB. Record and play back data.
The optical pickup 3 can be moved in the sledge direction by a seek motor (not shown). The focus actuator, the track actuator, and the seek motor are controlled by the motor driver 14 and the servo unit 15 based on signals obtained from the light receiving element and the position sensor so that the spot of the laser beam LB is located at a target position on the optical disc 1. Is controlled.
[0016]
When reading the optical disk 1 (reproducing and reading information), the reproduction signal obtained by the optical pickup 3 is amplified by the read amplifier 10 and binarized, and then input to the CD decoder 11. The input binary data is EFM (Eight to Fourteen Modulation) demodulated by the CD decoder 11.
It should be noted that the recording data is EFM modulated by grouping 8 bits at a time. In this EFM modulation, 8 bits are converted into 14 bits, and 3 combined bits are added to make a total of 17 bits.
In this case, the combined bits are attached so that the number of “1” and “0” up to that time are equal on average. This is called “DC component suppression”, and the slice level fluctuation of the DC-cut reproduction signal is suppressed. The demodulated data is subjected to deinterleaving and error correction.
[0017]
Thereafter, the data is input to the CD-ROM decoder 12, and further error correction processing is performed to improve the reliability of the data.
The data on which the error correction processing has been performed twice is temporarily stored in the buffer RAM 8 by the buffer manager 9 and transferred to the host computer via the ATAPI / SCSI interface 13 at once at a state in which the data is prepared as sector data. You.
In the case of music data, data output from the CD decoder 11 is input to the D / A converter 16 and is extracted as an analog audio output signal Audio.
[0018]
When writing (recording and writing information) on the optical disk 1, data sent from the host computer through the ATAPI / SCSI I / F 13 is temporarily stored in the buffer RAM 8 by the buffer manager 9.
The write operation is started with a certain amount of data stored in the buffer RAM 8. In this case, it is necessary to position the laser spot at the write start point before that. The point is determined by a wobble signal which is previously engraved on the optical disk 1 by meandering of the track. The wobble signal includes absolute time information called ATIP, and this information is extracted by the ATIP decoder 7.
The synchronization signal generated by the ATIP decoder 7 is input to the CD encoder 5 to enable writing of data at an accurate position on the optical disk 1.
[0019]
The data in the buffer RAM 8 is added with an error correction code and interleaved by the CD-ROM encoder 6 and the CD encoder 5, and is recorded on the optical disc 1 via the laser control circuit 4 and the optical pickup 3.
The EFM-modulated data drives the laser at a channel bit rate of 4.3218 Mbps (standard speed) as a bit stream.
In this case, the recording data forms an EFM frame in units of 588 channel bits. The channel clock means a clock having the frequency of the channel bit.
Each operation by the CPU 18 is performed by receiving a command from the host computer via the ATAPI / SCSI I / F 13. Data exchange is also performed via the ATAPI / SCSI I / F 13.
[0020]
Then, in the ROM 17 or the RAM 19, a procedure for recording and reproducing data so that the recording unit and the reproduction unit are different from each other on the recording medium, and the maximum recording address in the recording command instruction issued at the time of data recording to the computer. The procedure for recording as the total recording amount of recorded data, the data recording amount is accumulated for each recording command instruction issued at the time of data recording, and the accumulated data recording amount is the total recording amount of data recorded on the recording medium. , A procedure for recording a value specified by the host computer at the time of data recording as the total recording amount of data recorded on the recording medium, and a reproduction instruction to an address exceeding the total recording amount recorded on the recording medium. The procedure for prohibiting the instruction, and when the total recording amount recorded on the recording medium is an integral multiple of the recording unit, it is determined that the recording medium is a duplicated recording medium. Storing in advance a program for executing a procedure for.
[0021]
The program is recorded on a computer-readable recording medium such as a flexible disk, an MO disk, a CD-ROM disk, a CD-R / RW disk, a CD + R / RW disk, a DVD-R / RW disk, and a DVD + R / RW disk. Alternatively, the CPU may be installed in a RAM or the like via the recording medium so as to be executable. Further, the above program may be installed in a RAM or the like so that the CPU can execute the program from an external computer via various communication networks such as a local area network and the Internet.
[0022]
Therefore, the CPU executes the information recording / reproducing process for recording and reproducing data so that the recording unit and the reproduction unit are different on the recording medium, and sets the maximum recording address in the recording command instruction issued at the time of data recording. The process of recording the total amount of data recorded on the recording medium, the data recording amount is accumulated for each recording instruction issued at the time of data recording, and the accumulated data recording amount is the total recording amount of data recorded on the recording medium. The process of recording as data, the process of recording the value specified by the host computer at the time of data recording as the total recording amount of the data recorded on the recording medium, and the reproduction instruction instruction to an address exceeding the total recording amount recorded on the recording medium Prohibiting processing, and processing of determining that the recording medium is a duplicated recording medium when the total recording amount recorded on the recording medium is an integral multiple of the recording unit. Cormorant.
[0023]
That is, the CPU records and reproduces data so that the recording unit and the reproduction unit are different from each other on the recording medium, and sets the maximum recording address in the recording command instruction issued at the time of data recording to the data recorded on the recording medium. Means for recording as the total recording amount of data, and means for accumulating the data recording amount for each recording instruction issued at the time of data recording, and recording the accumulated data recording amount as the total recording amount of data recorded on the recording medium. Means for recording a value specified by the host computer at the time of data recording as the total recording amount of data recorded on the recording medium, and prohibiting a reproduction command instruction to an address exceeding the total recording amount recorded on the recording medium. And a function of determining that the recording medium is a duplicated recording medium when the total recording amount recorded on the recording medium is an integral multiple of the recording unit.
[0024]
Next, processing in the optical disk device will be described.
FIGS. 2 to 6 are flowcharts showing data recording / reproducing processing in the optical disk device shown in FIG.
As shown in FIG. 2, the CPU 18 executes the mounting process of the optical disc in step (indicated by "S" in the figure) 1, and in step 2, the total recording capacity (total recording amount, accumulated data recording amount) from the optical disc in step 2. Alternatively, a process for reading the maximum recording address is executed, and it is determined in step 3 whether the total recording capacity or the maximum recording address is recorded on the optical disc.
[0025]
If the total recording capacity or the maximum recording address is not recorded on the optical disc in the judgment in step 3, the maximum recording capacity (total recording capacity) = 0 or the maximum recording address = 0 in the memory (for example, the RAM 19) as an initial value setting in step 4. Is set, and the process proceeds to step 6 in FIG.
On the other hand, if the total recording capacity or the maximum recording address is recorded on the optical disc in the judgment of step 3, the total recording capacity read from the optical disc as the maximum recording capacity is set or set in the memory (for example, RAM 19) as an initial value setting in step 5. The maximum recording address read from the optical disk is set as the maximum recording address, and the process proceeds to step 6 in FIG.
[0026]
In step 6 of FIG. 3, the process enters a standby state for receiving a command from the host computer or the like. In step 7, it is determined whether or not a command has been received from the host computer or the like. Steps 6 and 7 are repeated until there is.
When the command is received in the determination of step 7, it is determined in step 8 whether or not the command is a designated value write command.
If it is determined in step 8 that the command is the designated value write command, in step 12 the total recording capacity in the designated value write command is stored as the maximum recording capacity in the memory (for example, RAM 19) (the initial value is updated), or the designated value is written. The maximum recording address in the command is stored (the initial value is updated), and the process proceeds to step 21 in FIG.
[0027]
If it is not the designated value write command in step 8, it is determined in step 9 whether the command is a write command (write command, data recording command, recording command command).
If it is determined in step 9 that the command is a write command, the process proceeds to step 13 in FIG. 4. If it is not a write command, it is determined in step 10 whether the command is a read command (read command, data reproduction command, reproduction command instruction).
If it is determined in step 10 that the command is a read command, the process proceeds to step 26 in FIG. 6. If it is not a read command, a process corresponding to another command is executed in step 11 and the process returns to step 6.
In step 13 in FIG. 4, it is determined whether or not the address range of the data recording destination on the optical disk designated by the host computer or the like overlaps the recorded area.
[0028]
If it is determined in step 13 that the address range of the recording destination does not overlap the recorded area, the amount of data to be recorded specified by the host computer or the like is added to the maximum recording capacity (total recording capacity) stored in the memory in step 14. The maximum recording capacity (total recording capacity) is updated, and the process proceeds to step 18 in FIG.
If it is determined in step 13 that the address range of the recording destination overlaps the recorded area, the process proceeds to step 15 to determine whether the address range of the recording destination is included in the recorded area.
If it is determined in step 15 that the address range of the recording destination is included in the recorded area, the process proceeds to step 18 in FIG. 5 while keeping the maximum recording capacity (total recording capacity) stored in the memory in step 17.
[0029]
If it is determined in step 15 that the address range of the recording destination is not included in the recorded area, the difference data amount obtained by excluding the data amount of the portion overlapping the recorded area from the data amount to be recorded instructed by the host computer or the like in step 16 is calculated. Then, the difference data amount is added to the maximum recording capacity (total recording capacity) stored in the memory to update the maximum recording capacity (total recording capacity), and the process proceeds to step 18 in FIG.
In step 18 of FIG. 5, the recording end address is obtained by adding the recording length to the recording start address specified by the host computer or the like. In step 19, it is determined whether or not the recording end address is larger than the maximum recording address stored in the memory. Judge.
If it is determined in step 19 that the recording end address is equal to or smaller than the maximum recording address, the process proceeds to step 21. If the recording end address is larger than the maximum recording address, the maximum recording address stored in the memory in step 20 is updated to the recording end address. Proceed to step 21.
[0030]
The data is recorded on the optical disk by the write processing in step 21, and it is determined in step 22 whether a close command (a command to close a session) has been received from a host computer or the like.
If the close command has not been received in the determination of step 22, the process returns to step 6 of FIG. 3 to repeat the above processing.
When the close command is received in the judgment of step 22, the maximum recording capacity stored in the memory is recorded in a predetermined area (for example, a lead-in area) of the optical disc as the total recording capacity of data in step 23 (the original total recording capacity is recorded). Or the maximum recording address stored in the memory is recorded in a predetermined area (for example, a lead-in area) of the optical disk (if the original total recording capacity is recorded, the overwriting is performed). May be).
[0031]
After that, the initial value of the memory is cleared (erased) in step 24, and the session closing process is executed in step 25, and this process ends.
In step 26 of FIG. 6, it is determined whether or not the address amount indicating the reproduction start position of the read command requested from the host computer or the like exceeds the total recording amount recorded on the optical disc. If the read processing is exceeded (if the access is out of the range), an error is notified to the host computer or the like in step 28 to execute the error processing for prohibiting the reproduction command instruction. Returning to step 6 in FIG. 3, the above processing is repeated.
[0032]
In the above-described processing, the case where the total recording capacity or the maximum recording address is recorded on the optical disc has been described. However, either one of them may be recorded, or both may be recorded. . The selection may be made, for example, by allowing the user to make a selection by a host computer and controlling the optical disc device to perform only the processing of the selected recording. Further, the processing may be performed according to the direction recorded on the optical disk. That is, when the total recording capacity is recorded on the optical disc, the processing for recording the total recording capacity may be switched, and when the maximum recording address is recorded, the processing for recording the maximum recording address may be switched.
[0033]
In this way, when the recording unit and the reproduction unit for the optical disc are different, the accurate total recording amount of data can be automatically recorded on the optical disc, and the usability can be improved.
In addition, the same effect as described above can be obtained in the case of performing data recording that is not sequential (recording is continuously performed from a small address to a large address on one side).
Further, the user can arbitrarily set the total recording capacity from a host computer or the like, and can record an accurate total recording capacity. Also, by setting the total recording capacity arbitrarily, the total recording amount can be given a special meaning or used for discriminating the original copy.
[0034]
Furthermore, by prohibiting the optical disc from accessing the total recording capacity or more, the behavior of the optical disc can be made more accurate.
For example, if access to an area that should not exist originally can be made without errors or other problems, it is highly likely that the execution of the program or OS will be hindered or an unexpected situation will occur. This can be useful for debugging, etc.
In other words, when playing back an optical disk on which the total recording capacity or the maximum recording address is recorded, even if possible, prohibiting access beyond the maximum recording address contradicts the reliability of data reproduction and data processing. Can be handled consistently.
[0035]
FIG. 7 is an explanatory diagram of a data recording format in a case where a take-out process is performed on an optical disc by recording halfway.
As shown in (b) of the figure, at the time of taking out an optical disk on which data has been recorded halfway, a block indicating that there is no more recorded area is written after that, and a head area (for example, a lead-in area) is written. 2.) Record and retrieve the content information in 20. Although the total recording capacity or the maximum recording address is recorded in the content information, as shown in FIG. 3C, conventionally, the total recording capacity or the maximum recording address determined based on the last address recorded is shown. The recording address record (the position indicated by (a) in the figure) is recorded in the first area 20, but in the optical disc apparatus of this embodiment, the total recording determined based on the last address specified by the host computer to record. The capacity or the maximum recording address (the position indicated by (b) in the figure) is recorded in the first area 20.
[0036]
Next, in the data recording / reproducing process of the optical disk apparatus, when the total recording capacity recorded on the optical disk is an integral multiple of the recording unit when the CPU 18 mounts the optical disk or the like, it is determined that the optical disk is a duplicated optical disk. Judge and notify the host computer or the like.
That is, in the optical disk on which data is not recorded by the optical disk apparatus of this embodiment, the total recording capacity and the maximum recording address are a multiple of a sector and an integral multiple of the recording unit (the normal address is counted from 0, so the maximum address +1 is not counted). However, this will not be taken into account here.) Therefore, it is possible to determine that the optical disc whose total recording capacity is an integral multiple of the recording unit is a duplicated optical disc.
[0037]
In some cases, the coincidence may occur by chance, but the larger the recording unit is, the lower the probability is. In addition, it can be prevented by setting the recording so that the recording does not always become a multiple. In this way, the total recording capacity and the maximum recording address are checked, and if the recording unit for each optical disc is known, it can be easily used for detecting the distinction between the original and the duplicate.
For example, the optical disk device of this embodiment can produce an optical disk having a total recording capacity different from the data amount actually instructed to be recorded. However, in many devices, this function is recorded, and the optical disk serving as the original is recorded. If the device is not valid, it is possible to detect a copy by utilizing that the copy made by many devices is always only an integral multiple of the recording unit.
[0038]
This makes it possible to detect originals and duplicates very simply and at low cost as compared with duplicate detection using an expensive dedicated system. In addition, since the data entity and the physical standard are not changed as compared with the existing methods, a flexible detection method that can control compatibility and reproducibility is provided.
The optical disk device of this embodiment can also record on a file system. Further, it can also be used as means for detecting an optical disk duplicated in an apparatus other than this optical disk apparatus. Further, the present invention can be applied to a write-once optical disk and a rewritable optical disk.
[0039]
In the above embodiment, an optical disk device such as a CD-R / RW drive has been described, but an optical disk device such as a CD + R / RW drive, a DVD-R / RW drive, a DVD + R / RW drive, and a magneto-optical disk such as an MO drive. Various information recording / reproducing devices such as a magnetic disk device such as a drive device, a hard disk drive, a flexible disk drive, an LS120 drive, and a ZIP drive, and a memory card device such as a nonvolatile RAM and a ROM can be similarly implemented.
[0040]
【The invention's effect】
As described above, according to the information recording / reproducing apparatus and the information recording / reproducing method of the present invention, the total recording amount of the data recorded on the recording medium is set to the same value as the recording amount by the recording operation instructed from the host computer or the like. Can be Further, according to the program and the recording medium of the present invention, a computer can easily realize the functions according to the present invention.
