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： PURPOSE:To control the rotation of a disk medium at a prescribed rotational speed by restarting it even in the case of occurring a step-out phenomenon in a disk device for driving the disk medium by a stepping motor. CONSTITUTION:A detection means 16 detects the fact that a driving current ID to be supplied to a driving means 27 from a current supply means 15 becomes larger than a prescribed value due to the step-out phenomenon of a stepping motor 14 and generates an over current detection signal h. A second control means 17 controls a first control means 26 based on the signal h so that the motor 14 again rotates at a prescribed sped corresponding to a control signal CEX from the means 26 when the rotational speed of the motor 14 is reduced due to the step-out phenomenon of the motor 14 without depending on the control signal CEX and the current ID become less than a prescribed value.

摘要： PURPOSE: To make a device have a high speed reproducing function of data and to reduce incidence of a read error which cannot be corrected. CONSTITUTION: An optical disk reproducing means 1 reproduces data with the prescribed data reproducing speed set by the optical disk or a data reproducing rate faster than a prescribed data reproducing rate. An error correction processing means 2 performs error detection and error correction for the prescribed data length, outputs reproduced data in which an error is already corrected, when error correction cannot be performed, a correction impossible error signal is outputted. A reproduction control means 3 sets the fastest data reproducing speed for the optical disk reproducing means 1 in an initial stage state, when reproduction cannot be performed without causing a correction impossible error even if reproduction is repeated by controlling the optical disk reproducing means 1 for data of the prescribed length in which a correction impossible error is caused, the means 3 sets a data reproducing speed slower than the present data reproducing rate for the optical disk reproducing means 1.

摘要： PROBLEM TO BE SOLVED: To reproduce both high quality and low quality recording medium disks at a speed as high as possible in keeping the stability by measuring an eccentric amt. at a track center hole of the disk. SOLUTION: A controller comprises a mode changeover signal generating means 66, an eccentric amt. measuring and deciding means (FMC) 101, a surface wobble measuring and deciding means 102 and a speed command data generating means (SCG) 75. Then, the FMC 101 has a counter 67 for measuring the eccentric amt., a frequency divider 58, a prescribed frequency generating means (FG) 69 and a comparing means 70. The output of the counter 67 and the output of the FG 69 are compared with each other by the comparing means 70, and this result is sent to the SCG 75. Then, when the eccentric amt. exceeds a prescribed amt., it is indicated by the SCG 75 that the present disk is the low quality disk. Then, the speed of the disk is lowered.
