Abstract
According to one embodiment, there is provided a magnetic recording medium having a data region in which a plurality of recording tracks, each including magnetic dots arrayed in a down-track direction with a pitch p, are formed in a cross-track direction, and a servo region including a preamble in which a plurality of lines of magnetic dots, which are arrayed in a cross-track direction with a pitch p, are formed at equal intervals in the down-track direction.
Claims2
A magnetic recording medium comprising:
- a data region in which a plurality of recording tracks, each including magnetic dots arrayed in a down-track direction with a pitch p, are formed in a cross-track direction;
- and
- a servo region including a preamble in which a plurality of lines of magnetic dots, which are arrayed in the cross-track direction with a pitch p along a curve corresponding to a locus of a read head attached to an actuator arm, are formed at equal intervals in the down-track direction,
- wherein the magnetic dots are arrayed with same periods both in the data region and the servo region.
