Abstract

PURPOSE:To execute the dislocation correction for securing the positioning accuracy, by moving a head and extracting the position information from a track for servo-information, and correcting the dislocation of a block unit, when a connection selecting signal from a host device is disconnected. CONSTITUTION:The data recording surface is divided into prescribed plural blocks BK1-BK3 by utilizing one face of the data recording surface and using a set of continuous plural pieces of plural data recording tracks existing on the same surface, as one block, and at least one piece of data recording track in the vicinity of the center of respective blocks BK1-BK3 is arranged as tracks SVT1-SVT3 for servo-information in which plural pieces of position information are written continuously extending over the whole periphery of the track. In this state, when a connection selecting signal from a host device is disconnected, the dislocation of a block unit is corrected by moving a head and extracting the position information from the arranged tracks SVT1-SVT3 for servo-information. In such a way, the dislocation correction for securing the positioning of high accuracy can be executed.
