Filed: 1993-08-17
Abstract: PURPOSE:To enhance the quality of a recording mark reproducing signal by recording a mark erasing a phase deviation between the rear edge position of the mark recorded on a magnetic film of a disk and a falling position of a laser beam emitting pulse current. CONSTITUTION:A parallel signal is modulated to a disk code signal by a conversion part 12. When a disk code and a synchronizing signal by one round of a track are obtained by a pattern generating unit 19, the pulse current is sent to an optical head 14 by a laser driving circuit 13, and a laser beam irradiates the magnetic film of the disk 1, and external magnetic field is applied, and the magnetic film is magnetized by a bias magnetic circuit 15, and a recording mark corresponding to the pulse current is formed. On the other hand, by the pattern generating unit 19, the end positions of respective disk code signals by one round of the track are stored, and a corresponding erasure mark signal and its synchronizing inversion signal are outputted to the laser driving circuit 13 and the bias magnetic circuit 15, and an erasure mark is formed. The front edge position of the mark coincides with the falling position of the pulse current in the phase, and a superposition part between the recording mark and the erasure mark is erased, and the phase deviation between the rear edge position of the recording mark and the falling position of the pulse current is eliminated.
