Abstract
PURPOSE:To stably generate a lead pulse detecting window by absorbing a dispersion of an electromagnetic conversion characteristic between tracks, and to improve an error rate of a device, by generating the lead pulse detecting window from lead pulse detecting window generating information which has been recorded in recording information on the track. CONSTITUTION:A recording format of a magnetic disk device is formed by a gap part 1, an ID format part 2, and a data format part 3. The ID format part 2 is formed by an SYNC part 6, an AL part 7 which has recorded information used for generating a lead pulse detecting window, an AM part 8, an ID part 9, and a CRC part 10, and the AL part 7 is formed by an isolated bit recording pattern part 4 and a 3-bit recording pattern part 5. Also, a 3-bit pattern and an isolated pattern are recorded as detecting window generating information in each track, and at the time of reproduction, by reading the respective peak amplitudes, its intermediate value is set to a window setting level. In such a way, the lead pulse detecting window can be generated stably, and an error rate of the device is improved.
