Title: Data recording method
Inventor: SHIN KAZUMA
IPC: G11B20/18
Filed: 1987-01-20
Abstract: PURPOSE:To simplify the constitution in both the hardware and software by recording an erroneous data recording area and recording a signal representing a thrown block together with a signal so as to read a correct data only by accessing the recording medium sequentially. CONSTITUTION:When a recorded data by one block has an error of one sector only, a system controller 7 records a signal having an error to a 2nd flag data 33 of the sector having the error, reads the correct data out of the recorded data in error from a 1st RAM again, gives it to an encoder 5 and it is recorded again on an alternate sector 23 in the same block. On the other hand, if the recorded data error by one block is two sectors or over, all the data are read again from the 1st RAM and recorded again in the next block. In this case, the system controller 7 throws away the block where two sectors or over of the data error exist and records the address of the block to a 2nd RAM.

Title: Phase synchronization circuit
Inventor: HIRANO AKIHIKO
IPC: H03L7/093
Filed: 1992-01-24
Abstract: PURPOSE:To reduce the jitter of a VCO clock and to improve the reliability of data read-out by generating a signal having a pulse width exceeding the pulse width within which a charger pump can respond and avoiding a non- sensible band at stable time. CONSTITUTION:Each time a read-out signal 11 is inputted, a charge or discharge signal is outputted to a charger pump for a certain period of time. Under this state, being stabilized, the system controls a phase error signal so that a same amount of operation having inverted polarity can be made with respect to charging or discharging which is performed normally. That is, the phase error signal is equivalent to the pulse width of a charge or discharge signal for the certain period of time to be outputted to the charger pump 3. Thus, by setting the pulse width to minimum time or more within which current switches 29 and 30 of the charger pump 3 can respond, the closed-loop state of the system at the stable time can be avoided.
