Title: Optical disk medium and optical disk recording/playing- back device and method
Inventor: KOBAYASHI SEIJI
IPC: G11B7/0045
Filed: 2001-04-24
Abstract: PROBLEM TO BE SOLVED: To substantially double the efficiently usable frequency band by separating an MTF into the positive frequency range and the negative frequency range. SOLUTION: The digital information to be recorded on the optical disk medium is recorded as independent signals respectively to the reflected or diffracted rays to the forward direction and the backward direction with respect to the progressive direction of a track on the optical disk medium. When the optical disk medium is manufactured, the digital information is bisected and a complex modulation signal is generated by changing the positive and negative frequency components in accordance with each digital information, then, the laser beam is modulated on the basis of the complex modulation signal.  Meanwhile, when the optical disk device is played back, a part of the digital information is decoded from the reflected or diffracted ray in the forward direction with respect to the progressive direction of the track, and another part of the digital information is decoded from the reflected or diffracted ray in the backward direction.
