Abstract

PURPOSE:To prevent an error from being generated in the reproduction or recording of data and to obtain a desired recording capacity, by regulating the position of a recording track at the inner peripheral side of a magnetic disk of high-order class at the outer peripheral side of the magnetic disk of low-order class. CONSTITUTION:In the magnetic disk 11 of high-order class, the recording track TR5 is formed with P1/4 of a track pitch P5 so that track density can be set at four times that of the recording pattern PT1 of the magnetic disk 1 of low- order class. As for the recording pattern PT5, it is formed at a part on the outer peripheral side of the magnetic disk 11 comparatively, on the other hand, no recording track PT5 is formed at a part ERIN on the inner peripheral side. In other words, the titled system is constituted in such a way that the position of the innermost peripheral recording track of the second magnetic disk 11 with high track density is regulated at the outer peripheral position other than that of the innermost peripheral recording track of the first magnetic disk 1 with low density. In such a way, it is possible to prevent the error from being generated at the time of reading out or writing the data, and to obtain the magnetic disk with large in recording capacity.
