Abstract
Servo sector numbers for identifying servo areas are recorded at predetermined positions in the respective servo areas on a disk. A plurality of data sectors are arranged between the respective servo areas. When a data sector is to be accessed, a servo circuit extracts a corresponding servo sector number. A CPU generates a data sector pulse at a timing corresponding to the start position of the data sector on the basis of the extracted servo sector number. The start position of the data sector is accurately detected in accordance with this data sector pulse, thereby reliably performing data access.
