Patent ID: 7203144

Claim:
An information recording apparatus comprising: a rotation drive section that supports and rotates a master disk having a resist layer formed thereon; an exposure beam emitting section that deflectably applies an exposure beam to the master disk to form a spot of the exposure beam thereon; a relative movement drive section that translates the rotation drive section relatively to the spot in a radial direction of the master disk; an emission controller that supplies the exposure beam emitting section with an instruction for modulating an intensity of the exposure beam according to data to be recorded; a movement controller that supplies the relative movement drive section with an instruction for moving the rotation drive section together with the rotating master disk by a predetermined moving amount for each rotation of the master disk; and a deflection controller that supplies the exposure beam emitting section with instructions for deflection operations for deflecting the exposure beam in a manner that the spot is successively moved from a first exposure start position in an opposite direction to a moving direction of the rotation drive section and then, at a point in time when the spot has moved up to an exposure stop position of the master disk in predetermined rotation thereof, the spot is intermittently moved to a second exposure start position in the moving direction of the rotation drive section, and wherein the spot is periodically returned to the first exposure start position, by successively moving the spot from the second exposure start position in said opposite direction.
