摘要： PROBLEM TO BE SOLVED: To increase the detectable ranges while improving the flexibility in designing patterns. SOLUTION: Two sets (M sets) of burst patterns BP1a, BP2a have two kinds of burst signal units (recess 40b) different in distance from the center of the data track pattern 40t but equal in radial length L11, and have a (2 M/N) track pitch of a length L10. They are formed in a manner that four (2M) centers C1a, C2a, C1a, C2a exist with an interval of the track pitch (1/N) within the range that their both ends do not match the centers C1a, C2a, C1a, C2a of the burst patterns BP1a, BP2a, BP1a, BP2a. In two kinds of burst signal units, their both burst signal units do not overlap in the direction of rotation, and the centers separate from one another in the radial direction by only a 2/2 ("M/N") track pitch, and their ends facing one another in the radial direction in both burst signal units separate from one another, where M and N are two or larger natural numbers.

摘要： PROBLEM TO BE SOLVED: To inspect whether there is a defect of servo-pattern, and the location of the defect, without performing a tracking servo control. SOLUTION: In inspecting a magnetic disk 100, signal read processing and head position change processing are alternately and repeatedly executed. In the signal read processing, magnetic signals are read at least for one turn while rotating the magnetic disk 100 and keeping a magnetic head 12, of which the read-width is equal to or less than a track pitch of the servo track, located at a predetermined radial position of rotation (positions on a broken line L1 or the like). In the head position changing processing, the rotation radial position where the magnetic head 12 is located is changed by a predetermined amount in the radial direction of the magnetic disk 100. Signal levels of the magnetic signals read in the signal read processing are digitized at predetermined time intervals. The data for specifying the signal level of the magnetic signal of each position, is generated as data to be inspected. The magnetic disk 100 is inspected based on the data to be inspected and reference data for inspection. COPYRIGHT: (C)2010,JPO&INPIT
