Title:
OPTICAL DISK DEVICE AND OPTICAL DISK REPRODUCING METHOD
Document Type and Number:
Japanese Patent JPH1064068
Kind Code:
A
Abstract:
To reproduce both of the data recorded on a land and a groove on an optical disk in an optimum characteristic.
A system control circuit 22 outputs a switch signal to a switch circuit 44 of a tracking servo circuit 41 according to specification of land reproducing, groove reproducing of an optical disk 10, and outputs the switch signal to the switch circuit 16 also to switch a waveform equalizer circuit 14 optimizing the characteristic of the regenerative signal of the land with the waveform equalizer circuit 15 optimizing the characteristic of the regenerative signal of the groove.
