Title: Optical disk device
Inventor: FUKUHISA SATOSHI
IPC: G11B11/105
Filed: 1996-06-14
Abstract: PROBLEM TO BE SOLVED: To provide an optical disk device capable of obtaining an excellent recording/reproducing characteristic and reducing a load applied to a light source by reducing a change in a reproduction C/N depending on a linear velocity. SOLUTION: Recording power PW between the recording power PW and bias power PB is set so as to become high in proportion to the linear velocity as shown by a solid line 11 similar to a usual device in a recording section on an optical disk from the position of the lowest linear velocity V1 to the highest linear velocity V2 . On the other hand, the bias power PB is set so as to become high in proportion to the linear velocity as shown by the line 12 different from the usual device in this case. However, its change rate is set so that a recording modulation degree becomes a fixed value independently of the linear velocity. A reproduction C/N characteristic is improved than the usual device in an area where the linear velocity on the optical disk is late, and the load applied to the light source is reduced.
