摘要
A servo-frame recording apparatus includes: a sector information rearranging section for rearranging serial bits of the sector information that is binary data; a first ExOR section for performing the ExOR (exclusive OR) on the sector information, the serial bits of which have been rearranged by said sector information rearranging section, and the track information, so that an exclusive logical sum is obtained; and a writing section for wiring the exclusive logical sum obtained by said ExOR section into the servo frame. With this configuration, a data length required for recording gray information and sector information can be shortened without lowering the reliability of a magnetic disk.
