Title: Optical disk device
Inventor: AMARI SHINICHI
IPC: G11B20/10
Filed: 1988-11-21
Abstract: PURPOSE:To improve reliability by reporting the deterioration in the quality of an optical disk medium when a threshold level of a quality control data to be edited reached a prescribed value or over by providing a quality monitor means. CONSTITUTION:When an instruction from a host system A is received, an object address included in the instruction is calculated by an instruction decoding means B and the processing of recording-reproduction-erasure is applied to an optical disk medium E. Only the data for quality control in a processed resulting data signal 4 is edited by a quality monitor means F, which gives an instruction signal 5 to record the result to a quality monitor data area of the medium E again. Then a recording-reproduction-erasure means C receives the signal 5 to apply recording processing to the medium E. When the quality control data edited by the monitor means F exceeds a prescribed threshold level, the deterioration in the quality of the medium E is reported to the system A via the means B, C. Then the recovery disable due to the deterioration in the quality of the medium E is avoided to improve the reliability.

Abstract: PURPOSE:To send a clock without noise production by synchronizing a control signal with a non-.selection clock and delaying the synchronization output by a half clock cycle so as to gate the non-selection clock signal. CONSTITUTION:An AND gate 40 receives a control signal (a) sent from a preceding circuit and an output signal g1 from an inverter gate 71 and outputs an output signal f0.
