Description

  The present invention relates to a data recording / reproducing apparatus and a data library apparatus.

  As background art of this technical field, there is JP-A-2004-192680. This publication describes as a problem that “a disk device that can use a plurality of recording media of different standards provides a disk device that has an effect of shortening the time until setup is completed”. Further, as a solving means, “a disk device capable of using a plurality of recording media of different standards is configured so that the disk type (standard) of the recording medium for which the setup process is given the highest priority can be specified (set) in advance”. It is described.

JP 2004-192680 A

  In Patent Document 1, the time required for the setup process is shortened by starting disc type determination from determining whether or not the disc is the highest priority type optical disc designated in advance. However, even if it is determined whether or not the optical disc is the highest priority type designated in advance, it is more BD-R (Blu-ray) than a read-only disc such as a BD-ROM (Blu-ray Disc Read Only Memory). Recording type discs such as (Disc Recordable) take a long time to set up. This is because the number of adjustment points for recording data increases, and unlike the BD-ROM in which data is written in advance, the initial data is not written in the BD-R.

  For example, the BD-ROM setup process includes a process for obtaining an optimum value of various settings by reproducing a data area and searching for a point where the amplitude value is maximized. However, in the BD-R setup process, in consideration of the case where the data area is not recorded, regardless of whether the data area is recorded or not recorded, for example, the optimum values of various settings are obtained only by the pre-write area of 32 clusters. During the process, seeks were required many times, and the setup process time was long.

  Further, when considering a data library apparatus, one optical disk may be recorded and reproduced by a plurality of drives. In this case, a good setup value of an optical disk in a certain drive is not necessarily a good setup value in another drive.

  Accordingly, an object of the present invention is to provide a data recording / reproducing apparatus and a data library apparatus that can shorten the setup processing time.

  The object of the present invention can be achieved, for example, by preparing a good setup value for each drive for one optical disk.

  ADVANTAGE OF THE INVENTION According to this invention, the data recording / reproducing apparatus and data library apparatus which can shorten a setup process time can be provided.

  Embodiments will be described below with reference to the drawings.

  FIG. 1 is a block diagram showing the configuration of the data recording / reproducing apparatus according to the first embodiment of the present invention. A data recording / reproducing apparatus 1 records data input from a host computer on a recording medium. Also, the data reproduced from the recording medium is output to the host computer. Reference numeral 2 denotes a data recording medium, for example, a BD-R (Blu-ray Disc Recordable). In the following description, the optical disk 2 will be described. The data recording medium is not necessarily limited to the optical disk, and may be a recording medium such as a magneto-optical disk or a hologram, and may not be in the shape of a disk.

  An optical pickup 3 reproduces a signal from the optical disc 2 and sends it to the amplifier circuit 4. Further, the modulation signal sent from the signal processing circuit 5 is recorded on the optical disc 2.

  An amplification circuit 4 amplifies a signal reproduced from the optical disc 2 via the optical pickup 3 and sends the amplified signal to the signal processing circuit 5. A servo signal is generated and sent to the servo circuit 8. The amplifier circuit 4 is mounted by, for example, AFE (Analog Front End).

  Reference numeral 5 denotes a signal processing circuit, which demodulates an input signal to solve the interleaving, performs error correction, and sends the scrambled data to the interface circuit 6. The data sent from the interface circuit 6 is scrambled, an error correction code is added, interleaved, modulated, and sent to the optical pickup 3.

  Reference numeral 6 denotes an interface circuit which sends data sent from the signal processing circuit 5 to the host computer. Also, the data sent from the host computer is sent to the signal processing circuit 5. The interface circuit 6 performs data transfer based on, for example, a SATA (Serial Advanced Technology Attachment) or other transfer method.

  Reference numeral 7 denotes a CPU (Central Processing Unit) which controls the recording process and the reproduction process of the data recording / reproducing apparatus 1. Further, setup information optimum for recording / reproducing the optical disc 2 is acquired. Also, identification information and medium information are read from the optical disc 2. The identification information is, for example, a product number or serial number recorded in a BCA (Burst Cutting Area) on the inner periphery of the optical disc. The medium information is information necessary for recording / reproducing the optical disc, such as the type of optical disc and defect management information, and is information read from the optical disc every time the optical disc is loaded. Note that an arbitrary control circuit or a dedicated circuit such as an ASIC may be used instead of the CPU.

  A servo circuit 8 controls the optical pickup 3 with a servo signal generated by the amplifier circuit 4.

  Next, the operation of the data recording / reproducing apparatus 1 when recording data on the optical disc 2 will be described. When the optical disk 2 is mounted on the data recording / reproducing apparatus 1, the CPU 7 reads the identification information of the optical disk 2 through the optical pickup 3, the amplifier circuit 4, and the servo circuit 8, acquires the setup information, and acquires the amplifier circuit 4 and the servo circuit. Set the optimal value to 8. Further, medium information is read from the optical disc 2 through the optical pickup 3, the amplifier circuit 4, and the signal processing circuit 5. Note that acquiring setup information and medium information from an optical disk and making various settings is generally referred to as setup processing.

  When the data is sent from the host computer to the data recording / reproducing apparatus 1, the data is received by the interface circuit 6, scrambled by the signal processing circuit 5, added with an error correction code, interleaved, data modulated, and optically modulated. The image is sent to the pickup 3 and recorded on the optical disc 2.

  Next, the operation of the data recording / reproducing apparatus 1 when reproducing data from the optical disc 2 will be described. When the optical disk 2 is mounted on the data recording / reproducing apparatus 1, the CPU 7 reads the identification information of the optical disk via the optical pickup 3, the amplifier circuit 4, and the signal processing circuit 5, acquires the setup information, and acquires the amplifier circuit 4 and the servo circuit. Set the optimal value to 8. When data is requested from the host computer to the data recording / reproducing apparatus 1, the signal read from the optical disk 2 through the optical pickup 3 is amplified by the amplifier circuit 4, the data is demodulated by the signal processing circuit 5, and the interleaving is released. Then, error correction is performed, descrambling is performed, and data is sent to the host computer via the interface circuit 6.

  FIG. 2 is a flowchart showing the operation of the data recording / reproducing apparatus of the first embodiment. When the optical disk is loaded in the data recording / reproducing apparatus, identification information reproduction setup processing is performed in step S201, and identification information is read from the optical disk in step S202.

  In step S203, recorded disk setup processing is performed. The recorded disk setup process is a setup including a process for obtaining various settings as optimum values when the amplitude value of the reproduction signal in the recorded data area is maximized, for example. Since any part of the optical disk can be reproduced as long as the entire surface of the optical disk is recorded, no seek is required. On the other hand, in the unrecorded disk setup process, for example, the pre-write area of the management area is reproduced to obtain the optimum values of various settings. However, since there are only 32 clusters, it is necessary to repeatedly seek during the process. . For this reason, in general, the unrecorded disk setup process takes longer than the recorded disk setup process.

  Next, in step S204, it is confirmed whether or not a setup error has occurred. If the setup error has occurred, it is determined that the disk is an unrecorded disk. Since the recorded disk setup process reproduces the recorded data area as described above, a setup error occurs in the case of an unrecorded disk with no recorded data area. Therefore, when a setup error occurs, it can be determined that the disc is an unrecorded disc.

  In step S206, data recording / reproduction processing is performed in response to a data recording / reproduction request from the host computer.

  With the above configuration, in the first embodiment of the present invention, when an optical disk is loaded, first, a setup process for a recorded disk is performed. If a setup error occurs, it is determined that the disc is an unrecorded disc, and setup processing for an unrecorded disc is performed. Since the setup process for the unrecorded disk is performed only when a setup error occurs, the setup process time for the recorded disk can be shortened.

Alternatively, data is reproduced from the optical disk and sent to the network 93 via the server 92. Reference numeral 92 denotes a server which manages the data sent from the network 93 by controlling the hard disk 94 and the data library device 91.

Further, for example, if the device numbers of the data recording / reproducing devices 101, 102, 103, 104 are made to correspond to 1, 2, 3, 4, and written into the memory 98 as one of the setup information, the setup information of the optical disc is the same. It is possible to know whether the data was obtained with this data recording / reproducing apparatus, and can be used as a reference for various adjustments. Alternatively, all setup information for each data recording / reproducing apparatus may be written in the memory.

  FIG. 10 is a block diagram showing the configuration of the data recording / reproducing apparatus of the fourth embodiment. The description of the same circuit as in FIG. 1 is omitted. A data recording / reproducing apparatus 101 records data input from the library apparatus control circuit on an optical disk.

Further, medium information and setup information are input from the memory via the library apparatus control circuit when the optical disc is loaded, and medium information and setup information are output to the memory via the library apparatus control circuit when ejecting.

  Although the data recording / reproducing apparatus 101 has been described, the data recording / reproducing apparatuses 102, 103, and 104 are the same.

  FIG. 11 is a flowchart showing the operation of the data library apparatus of the fourth embodiment. If there is a data reproduction request or data recording request in the data library apparatus in step S1101, the corresponding optical disc is loaded in the data recording / reproducing apparatus in step S1102. Here, for example, it is assumed that it is attached to the data recording / reproducing apparatus of apparatus number 1.

  Next, setup processing for reproducing identification information is performed in step S1103, and identification information is read from the optical disc in step S1104.

  Next, in step S1105, if the medium information corresponding to the identification information and the setup information are in the memory, and if one device number of the setup information matches in step S1106, the medium information and the setup information are read from the memory in step S1107. Is read. Here, since the case where the optical disk is mounted on the data recording / reproducing apparatus of apparatus number 1 is taken as an example, the case where the apparatus numbers match is the case where information of apparatus number 1 is stored in the memory. In step S1108, a recorded disk setup process is performed using the medium information and setup information read from the memory. Since the setup information is the information of the apparatus number 1 itself, it is possible to obtain the optimum setting value in a short time by setting the various setting values of the setup information as they are and using the various setting values of the setup information as a central value.

  If the medium information corresponding to the identification information and the setup information are present in the memory in step S1105, and if there is no information that matches the device number in step S1106, the medium information is read from the memory in step S1109. Here, since the case where an optical disk is mounted on the data recording / reproducing apparatus of apparatus number 1 is taken as an example, the case where there is no information that matches the apparatus number means that the information of apparatus number 1 is not stored in the memory, and the apparatus This is a case where information of numbers 2, 3, and 4 is stored. In step S1110, recorded disk setup processing is performed using the medium information read from the memory. In step S1111, setup information including identification information, medium information, and a device number is written in the memory.

  Alternatively, the medium information and setup information may be read from the memory in step S1109, and the recorded disk setup process may be performed using the medium information and setup information read from the memory in step S1110. Therefore, various setting values of the setup information cannot be set as they are. This is because the optimum setting value of a certain data recording / reproducing apparatus is not necessarily the optimum setting value of another data recording / reproducing apparatus. However, the optimum setting value can be obtained with reference to various setting values of the setup information obtained by another data recording / reproducing apparatus.

  If there is no medium information corresponding to the identification information in the memory in step S1105, an unrecorded disk setup process is performed in step S1112, the medium information is read from the disk in step S1113, and the identification information and medium information are read in the memory in step S1114.

  In step S1115, data recording / reproduction processing is performed in response to a data recording / reproduction request from the host computer.

  In general, a server temporarily records data sent from a terminal connected to a network in a hard disk, and then moves the data to a data library device when a predetermined condition is satisfied, for example, when there is no access from the terminal for a certain period of time. . At this time, the data library apparatus attaches an unrecorded disk to the data recording / reproducing apparatus, and records data on the disk. Since the disk is mounted for the first time, there is no medium information and setup information in the memory, but after that, the medium information is read from the disk and written to the memory, and the setup information obtained by performing the disk setup process is written to the memory. In order to record user data, the medium information and the setup information are stored in the memory unless the optical disk is loaded for the first time.

  FIG. 12 is a table showing an example of identification information, medium information, and setup information written in the memory of the data library apparatus of the fourth embodiment. The medium information and the setup information read from the optical disk are written in the memory together with the identification information, and the medium information and the setup information corresponding to the identification information are read from the memory when the optical disk is mounted on the data recording / reproducing apparatus. Since the medium information is written in the memory, it is not necessary to read the medium information from the disk again, and at least the time for reading the medium information from the disk can be reduced. Further, since the setup information is written in the memory as the setup adjustment result, various adjustment processes can be reduced or simplified, and the setup process time of the optical disc can be shortened. Further, since the device number of the data recording / reproducing device that has acquired the setup information is written, the processing can be switched depending on whether there is a corresponding device number. If there is a corresponding device number, the various setting values of the setup information can be set as they are, and the optimum setting value can be obtained in a short time with the various setting values of the setup information as the central value. If there is no corresponding device number, the optimum set value can be obtained with reference to various set values.

  For example, there are three set-up information for the BD-R with product number 126Ch and serial number 00001981h. This is setup information for device numbers 1, 2, and 4. If the disc is mounted on a data recording / reproducing device with device number 1, setup information for device number 1 is read out and setup is performed. When it is attached to the data recording / reproducing apparatus, the setup information of apparatus number 2 is read and setup is performed. When it is attached to the data recording / reproducing apparatus of apparatus number 3, for example, the setup is performed with reference to the setup information of apparatus number 1.

  The present embodiment can also be rephrased as follows. That is, in a data library device that records and manages data on a plurality of recording media, a plurality of data recording / reproducing devices that record / reproduce data on / from the recording medium and a recording that exchanges the recording media of the plurality of data recording / reproducing devices A medium exchanging device, storage means for storing identification information of the recording medium, and setup information for each data recording / reproducing device are provided, and the plurality of data recording / reproducing devices are for recording / reproducing on a recording medium under appropriate recording / reproducing conditions.
