Abstract

PURPOSE: To excellently read a data by providing a guard region not applying recording/reproduction before and after a boundary between a data reproduction exclusive area and a data recording area to record the data freely to a reproduction exclusive optical disk and stably retrieve the data.
CONSTITUTION: A guard area 9a having no data recorded is provided to a data reproduction exclusive area 4 and a guard area 9b without data recording is provided to a data recording area 3. Since no data is to be recorded or no data is recorded in the guard areas 9a, 9b in an optical disk 1, the areas have no retrieval start address and no retrieval object address. When the guard areas 9a, 9b have the number of tracks larger than that of a retrieval error and the data recording area 3 is retrieved from the data reproduction exclusive area 4, since the track of an object area is accessed even to the worst case after coarse retrieval is applied by a linear motor 30, the fine retrieval is applied in the same area of the data recording area.
