Claims

[Scope of utility model registration request]

(1) A magnetic disk fixed to a spindle, a disk rotation motor coupled to the spindle, a magnetic head that is in contact with the disk at least during a period when the rotation of the disk is stopped, and the magnetic head. a head moving mechanism for moving the head substantially in the radial direction of the magnetic disk; a head moving motor for moving the magnetic head via the head moving mechanism; and a holding mechanism configured to hold the head moving mechanism so as to keep the magnetic head in contact with the magnetic head, and to be released from the holding by driving the head moving motor. Device.

(2) The magnetic disk device according to claim 1, wherein the head moving mechanism includes a head carriage to which the magnetic head is attached.

(3) The holding mechanism includes a roller or a protrusion provided on the helad carriage, and a recess into which the roller or protrusion is received so that it can escape when the magnetic head is located in a portion other than the effective recording area. A magnetic disk device according to claim 2 of the utility model registration claim, which comprises:

(4) The holding mechanism includes a recess provided in the helad carriage, and a roller or protrusion that retractably enters the recess when the magnetic head is located in a portion other than the effective recording area. A magnetic disk device according to claim 2 of a certain utility model registration.
