Abstract
An information recording apparatus for recording tracks includes: a rotation drive section (RDS) that supports and rotates a master disk with a resist layer; an exposure beam emitting section (EBES) deflectably applying an exposure beam to the disk to form a spot thereon; a relative movement drive section (RMDS) translating the RDS relatively to the spot in a radial direction of the disk; an emission controller supplying the EBES with an instruction for modulating an intensity of the exposure beam according to data to be recorded; and a movement controller supplying the RMDS with an instruction for moving the RDS with the rotating disk by a predetermined moving amount for each disk rotation.
