PROBLEM TO BE SOLVED: To make a recording disk usable against the formats of non-sectored and sectored disks and the format of a tape by making a servo section independent from a data architecture for which sampled rates are used. SOLUTION: Fields 32, 37, and 38 are used for partial writing during writing operations and fields 33 and 35 are used for writing only during servo writing operations. Therefore, each servo sector 30 is composed of the bit in a position error signal PES field 30 containing positional information and the bits in the fields which are provided on both sides of the PES field 35 for controlling the interruption and restoration of data writing and reading. |
