Title: Information recording and reproducing method, and device therefor
Inventor: HANANO MASAAKI
IPC: G11B20/12
Filed: 1997-01-14
Abstract: PROBLEM TO BE SOLVED: To increase the recording capacity by making the recording density or recording method different between the track of a projecting part and the track of a recessing part, when the recording and reproducing of a signal or only the reproducing of a preliminarily recorded signal is performed in both of tracks of the recessing part and the projecting part on an information recording medium. SOLUTION: When a high-density recording and reproducing is performed on the land 10 side or the groove 11 side of an optical disk 1, an optical head 2 or 2' using a semiconductor laser 20 whose wavelength is shorter or a semiconductor laser 20' is used. A control part 4 changes over light quantities of semiconductor lasers 20, 20' in order to record information and performs on/off controls of the optical heads 2, 2' and reproduces information by receiving RF reproduced signals. Thus, both of the land 10 and the grove 11 are used as information tracks and the both are made to be recordable by making recording densities of them different. Thus, recording capacity is increased and, moreover, since even a device for low-density recording and reproducing can reproduce an optical disk which is recorded by this device, a problem of compatibility is eliminated.
