Title: Magnetic disk device and control method
Inventor: TOYAMA SOICHI
IPC: G11B5/39
Filed: 1995-01-09
Abstract: PURPOSE: To restrict the conduction of a sense current to a magneto-resistance effect head under the idle state for making low power consumption and longlife of the head in the magnetic disk device using the MR head. CONSTITUTION: A head positioning servo signal 12 is recorded in a part of a data surface, while a data head is formed by combining a data writing inductive head 19 and the reproducing MR head 1A. When the magnetic disk device where the servo signal is reproduced by the MR head is under the idle state, the sense current is conducted to the MR head at an optimum value at the time of reproducing the servo signal only, and in other cases, this conduction is cut off or the optimum value is decreased. Head positioning control processing is performed by a microprocessor 50, and in the idle state, sense current control is also performed via a register 55. The conduction/cut-off is made by a sense current switch 21, and the changeover of the current values is carried out by a constant current circuit 22.
