Magnetic recording/reproducing apparatus

摘要

A magnetic recording/reproducing apparatus is disclosed with which levitation of the magnetic head can be prevented in case of the speed of rotation of the magnetic disc is raised when a recording/reproducing is performed, the recording density and the transfer rate can furthermore be raised and the amount of abrasion of the magnetic head can be reduced. When a recording/reproducing operation with respect to a magnetic disc is performed, a magnetic disc is rotated by a spindle motor. A magnetic head included in a head structure supported by a suspension is operated to perform recording/reproducing with respect to the magnetic discs. At this time, the head structure is supported such that a load which is exerted from the head structure on the magnetic disc satisfies a range from 75 mgf to 500 mgf. Since the load which is exerted from the head structure on the magnetic disc is specified, the amount of abrasion of the magnetic head can be reduced, a stable state of contact between the magnetic disc and the head structure can be maintained and the recording density and the transfer rate can be raised.
