Abstract:
A method of formatting a storage medium into sectors format the sectors such that each contains an ID field for storing ID information. The ID information includes addresses of a plurality of sectors, preferably the address of the sector containing the ID field and the address of at least one subsequent sector. A drive unit for use with the storage medium formatted as described above reads the ID information from the ID field, and then temporarily stores either the ID information of a sector other than the sector containing the ID field or the result of an evaluation of the ID information, and refers to the stored ID information when the address of the sector corresponding to the stored information is later examined.
