ABSTRACT:
A servo information reproducing method reproduces servo information from a recording medium by a head, where servo regions recorded with the servo information and data regions recorded with data coexist on the recording medium. The servo information reproducing method includes a setting step for setting a sense current which is supplied to the head when reproducing the servo information from the servo region to a value larger than that of a sense current which is supplied to the head when reproducing the data from the data region.
