Abstract
When information is reproduced from a recording medium having a plurality of tracks with respective addresses, a head is moved relative to the recording medium in order to let the head make access to a target track. A memory is provided for storing information having been reproduced in the past by the head. When, in making the access, the head reaches another track as failing to make access to the target track, a controlling unit reads information of the other track reached and stores the information in the memory. In recording of information, when, in making the access, the head reaches another track as failing to make access to the target track, the controlling unit writes information in the other track reached.
