摘要：
An access of a device for writing or reading information from/to a desired region is performed in the following manner on an information recording medium on which a plurality of tracks are spirally formed. The recording medium is rotated and an arrival position of the writing/reading device is estimated when the device is accessed to a track on which the desired region exists. If the estimated position lies within the desired region, the writing/reading device is caused access to the track on which the desired region exists. If the estimated position is located after the desired region, the writing/reading device is caused to access one-preceding track of the track having the desired region.
