Embodiment Construction
[0071] Hereinafter, preferred embodiments of the information recording medium, recording and reproducing apparatus, and disk master of the present invention will be described with reference to the accompanying drawings.
[0072] The hard disk drive 1 shown in Fig. 1 is a magnetic recording and reproducing device as an example of the recording and reproducing device of the present invention, and its structure has: Data detection unit 6, drive 7, control unit 8, ROM 9, and magnetic disk 10a. In this case, as an example, the magnetic disk 10a is a discrete track type magnetic disk (patterned medium) capable of recording recording data by a perpendicular recording method, and corresponds to the information recording medium of the present invention. Specifically, as shown in FIG. 2 , the magnetic disk 10 a is formed on a glass substrate 11 in the order of a soft magnetic layer 12 , an intermediate layer 13 and a magnetic layer 14 . In this case, the magnetic layer 14 formed on the...
