ABSTRACT:
A magneto-optical disc recording and reproducing apparatus has the distinction of ID signal reproducing ability in read (reproducing) mode and in write (recording) mode. The disc recording format is based on sectors each including two identifiers in the address field. The apparatus analyzes a command from the host computer (step ST1). It sets the control parameter of write mode for the write command or the control parameter of read mode for the read command (steps ST4, ST5) so as to impose the distinction on the ID signal reproducing (readout) ability between read mode and write mode. Following the seek operation to the target track, it determines based on the ID signal detection as to whether a correct ID signal has not been retrieved from any of two identifiers in the target address field indicative of the error of ID signal reproduction (step ST7). It proceeds to the information writing or readout operation unless the ID signal reproduction ends in error (step ST8).
