Title: Phase difference tracking error signal generating circuit, phase difference tracking device and recording media
Inventor: MAEKAWA HIROSHI
IPC: G11B7/24085
Filed: 1997-03-28
Abstract: PROBLEM TO BE SOLVED: To obtain a PDP tracking error signal whose amplitude is large with respect to two kinds of media whose reflectivities are different and even to a phase transition optical disk whose reflectivity is low. SOLUTION: A recording media (optical disk) is inserted into a device (S1) to check the kind of the media (S2). At this time, when the reading of the media is performed by considering it a ROM (media whose reflectivity is high) and data are barely read, the media is judged from the data (S3). When the media is not a phase transition media, it is reproduced as the ROM media and when it is the phase transition media, a seeking operation is performed and the gain of a DPD signal is controlled (increased) (S4) to perform a tracking (S5) and the reproducing of the data is performed (S6). When the data can not be read, the media is detected as a phase transition media.
