Abstract

PURPOSE:To suppress the characteristic dispersion of a magnetic disk and a magnetic head by including even special information to control information to write a home address between an index mark and a data part. CONSTITUTION:In a counting part 3 of a control information area to write a home address 2 of a data track 1 between an index mark 6 of a magnetic disk and a data part 4, electromagnetic conversion characteristic information in accordance with the radius direction position of a track 1 is written besides the cylinder address of address information, head address and recording address information, the flag information of the use propriety of recording 5 and the position information of a defect medium after the recording 5. By the proper compensation in accordance with the electromagnetic conversion characteristic information, the characteristic dispersion of a magnetic disk and a magnetic head and so forth can be essentially suppressed. As a result, optimum writing and reading characteristics can be obtained.
