摘要： PROBLEM TO BE SOLVED: To provide an optical disk drive which flexibly and efficiently executes verification of recorded data. SOLUTION: A drive controller 320 sets an area to be verified and a mode of verification according to a command which is supplied from a host device. As the area to be verified, the user selects one or a plurality of lead-in, inner, middle, and outer areas. As the verification mode, the user selects one of an immediate execution mode and an in-close-command execution mode. In a duplicator or the like which records the same data onto a plurality of optical disks, the user can designate an important data portion and selectively execute verification.

摘要： PURPOSE: To obtain a compact disc reproducing device in which a target index of a target melody (track) in a compact disc can be searched quickly. CONSTITUTION: Variation is detected in the index number read out from the sub-code area of a CD 3 and the address (time data) of CD is detected at the time of variation. An HDD 27 stores a table indicating the relationship between the index number and the starting address of a track area sectioned by the index number. When a target index number is searched, it is judged whether information indicative of the index number and the starting address thereof are stored on the table in the HDD 27, or not. When the starting address of a target index number is stored in the table, an optical pickup 12 is positioned at that starting address. With such arrangement, searching time can be shortened.

摘要： PROBLEM TO BE SOLVED: To easily discriminate an optical disk apparatus used for recording data into an optical disk.
SOLUTION: After the power of laser light is adjusted by test write in a power calibration area (PCA) of the optical disk, data is erased from the power calibration area. When a new optical disk is loaded, if there is no trace in the power calibration area, it is determined that data has been recorded using an optical disk apparatus manufactured by the same company, or the disk is a brand-new optical disk. If there is a trace, it is determined that the data has been recorded using the optical disk apparatus manufactured by another company, and data recording is limited (S110).

摘要： PROBLEM TO BE SOLVED: To provide an optical disk reproducing device for operating efficient data transfer by saving the waste of the reproduction of the overlapped part of data from a CD-ROM by using the overlapped part of data at the time of the data storage, transfer, and abandonment of a buffer memory. SOLUTION: The overlapped part and overlapped amount of data stored in a buffer RAM and data to be stored in the buffer RAM the next are detected (S12), and the overlapped part is left in the buffer memory (S15-S17), and the other part except for the overlapped part is abandoned from the buffer memory. Therefore, the waste of the reproduction of the overlapped part from a CD-ROM again can be saved, and a time required for storing data can be shortened (S18). Thus, efficient data transfer can be attained.

摘要： PROBLEM TO BE SOLVED: To make it possible to execute the command processing without waiting until the TOC read processing of all discs ends, and to shorten waiting time of a TOC read processing by suspending an index reading processing to give priority to a command processing when a command is issued during the index reading processing to a disc following two sheets. SOLUTION: A changer 30 conveys a disc 11 housed in a disc housing unit 33 to a disc reproduction unit 32 to reproduce the disc 11 by a disc conveying mechanism. A local CPU for controlling the changer 30 monitors the presence of a command reception while a TOC processing of the remaining discs 11 is executed after the end of the TOC processing of the first disc among a plurality of discs 11 while the TOC processing is suspended when the command reception is detected during the TOC processing to give priority to the command processing.

摘要： PROBLEM TO BE SOLVED: To distinguish between copy guard and physical defects of an optical disk.SOLUTION: The presence or absence of defects is determined based on reproduction error at the time of data reproduction of an optical disk 10. When reproduction error occurs at L0 of a two-layer optical disk, a system controller 32 detects whether or not reproduction error occurs also at L1 at the same radial position. If reproduction error does not occur at L1, the cause is determined to be copy guard, and if reproduction error occurs also at L1, the cause is determined to be physical defects.

摘要： PROBLEM TO BE SOLVED: To provide a disk drive device in which current consumption and vibration of the device are reduced by limiting a reproducing speed when a mounted DVD is a DVD-VIDEO. SOLUTION: Presence or absence of protection for the contents of a disk is determined from the copyright control information of a mounted digital versatile disk. When protection is provided for the contents, the reproducing speed of the DVD-VIDEO is reduced to limit the reproducing speed of the disk and current consumption and vibration of the device are reduced as a result.

摘要： PURPOSE:To surely discriminate the presence and the absence of an optical disk in a short time by employing an optical pickup which discriminates the presence of an optical disk. CONSTITUTION:Reflected light is received from reflective surface including a reflective recording layer surface and a transparent film layer surface of an optical disk 12 by the focusing of light on an optical disk 12 by an actuator lens 14a of an optical pickup 14. A signal processing section 16 is provided to generate focus error signals in accordance with the focusing. Focus error signals are counted and the counted value is used by a disk presence and absence discrimination section 17a to discrimination whether the optical disk 12 is loaded or not.
