Title: Method for exposing optical master disk
Inventor: YAMADA YOSHIAKI
IPC: G11B7/26
Filed: 1988-09-09
Abstract: PURPOSE:To prevent the wear of the film of a pit and to stabilize the electrical characteristic of a medium by reducing the exposure power of a beam for exposing a V-groove for tracking when the address pit is formed by exposure on the master disk of an optical disk. CONSTITUTION:The exposure power of the laser beam for exposing the V- groove for the tracking exposed at the same time when an address pit 2 is formed by exposure on the master disk of the optical disk is reduced. Thus, the generation of the wear of the film of both sides of the address pit caused by the overlapping of the laser beams for exposing the V-groove and for exposing the address pit is prevented. Consequently, the sectional form of the address pit 2 becomes nearly rectangular. Even when there is the minute fluctuation of exposure conditions about the exposure power or interval of the two laser beams, the fluctuation of the sectional form of the pit 2 can be suppressed. Thus, the electrical characteristic of the optical disk medium copied from the master disk can be stabilized.
