Abstract

PURPOSE:To record between tracks by controlling a head scanning position so as to be an intermediate part between the adjacent tracks and recording data between the tracks based on a second clock signal in which a phase is dislocated by 180 deg.. CONSTITUTION:A first tracking error signal obtained by detecting a tracking pit and a second tracking error signal obtained by inverting the first tracking error signal can be switched by a first change over switch 10, by switching to this second tracking error signal, a tracking control is executed by defining the head scanning position to be the intermediate position of the adjacent tracks, a second clock signal in which the phase of a first clock signal obtained by detecting a clock pit is dislocated by 180 deg. is switched by a second change over switch 15, and data is recorded between the tracks based thereon. Thereby, a cross talk is suppressed to record the data between the tracks according to a simple constitution.
