Abstract
A magnetic disk device having a magnetic disk for recording information, a rotary mechanism for rotating the magnetic disk, a magnetic head unit for recording information on the rotating magnetic disk, a slider having mounted thereon the magnetic head unit and flying over the rotating magnetic disk, a magnetic head supporting mechanism for supporting the slider, and a positioning mechanism for setting the magnetic head unit at a predetermined radial position. The magnetic head supporting mechanism has mounted thereon an integrated circuit (IC) for amplifying an information write/read signal of the magnetic head unit, and a control circuit is connected to the IC. A recording frequency is controlled according to the radial position of the IC on the magnetic disk by the control circuit.
