Servo data is stably written even if the flying height of a head/slider is varied. In one embodiment, a seamed pattern of servo data is written by a write head that is equipped in a head/slider. A variation pattern signal of the flying height in the circumferential direction of a magnetic disk is generated. The write head is located at a given position of the magnetic disk. The seamed pattern is written while controlling a recording current to flow in the write head on the basis of the variation pattern. At a constant recording current, a pattern length L1 is shortened when a flying height H1 is higher, and a pattern length L2 is lengthened when a flying height H2 is lower. The magnitude of the recording current is controlled according to the variation of the flying height, thereby making it possible to fall a pattern length L within a constant range, and accurately define the position of an edge of the seamed pattern.

An extension rib extends from a pressing portion in the take-up direction of an ALR cam and is formed to be able to abut with an ALR pawl. Accordingly, when the ALR cam excessively rotates in the pull-out direction with respect to a set position in a maximal pulled-out state, the ALR pawl abuts the extension rib. Accordingly, it is possible to suppress a state in which the ALR pawl climbs over the pressing portion and engages with a V-gear. Namely, even if a rotation variation of the ALR cam becomes large by setting a speed reduction ratio of speed reduction mechanism to a small value, it is possible to absorb such variation by the extension rib. Thus, it is possible to absorb rotation variation of the ALR cam while improving accuracy of switching timing from the ELR(or ALR) state to the ALR(or ELR) state.
