Title: Optical master disk, optical disk recorder and optical disk recording method
Inventor: NAGASHIMA MICHIYOSHI
IPC: G11B7/00
Filed: 1988-12-09
Abstract: PURPOSE:To execute signal recording with high accuracy by providing grooves for eliminating eccentricity on the side inner than the innermost periphery or outer than the outermost periphery of the signal recording region of the optical master disk and adjusting the eccentricity while observing the grooves by a microscope. CONSTITUTION:Spiral V-grooves are formed on the optical master disk 11 and signals are recorded on the slopes of the V-grooves. The V-grooves 16 for eliminating eccentricity are formed concentrically on the side inner than the innermost periphery or outer than the outermost periphery of the signal recording region where the V-grooves are formed. The set position of the master disk 11 is adjusted to decrease the eccentricity while the grooves 16 on the master disk 11 are observed by the microscope in the case of installing the master disk 11 on a spindle. Since the V-grooves 16 on the master disk 11 and the V-grooves of the recording region 13 are concentric, the eccentricity of the V-grooves of the region 13 can be decreased as well. The signal recording is executed in this way by focusing the laser spot of a small aberration with high accuracy to the slopes of the V-grooves.
