Title: Perpendicular magnetic recording method
Inventor: KAWABATA TOMOYUKI
IPC: G11B5/02
Filed: 1988-04-21
Abstract: PURPOSE:To suppress recording demagnetization, to clarify a magnetization inverting position and to improved recording density by limiting a recording current to a prescribed value or below for a fixed time when switching the direction of the recording current supplied to a ring-type head. CONSTITUTION:An exclusive NOR gate 3, a delay circuit 4 and a TFF 2 are connected to the base of a TR connected to transistors TR1 and TR2 of a coil 1. When switching the direction of the recording current, an output Qe of the gate 3 is 'L' for the fixed time from when the Q output of the TFF 2 is inverted, thus, a base voltage Vb of the TR3 becomes low-level and recording currents i1 and i2 are limited to the prescribed value or below. Consequently, during this, a vertical magnetic field is weakened, a magnetization recorded on a medium before the switching, the recording demagnetization magnetized in the opposite direction immediately after the switching is suppressed, with the result that the magnetization inverting position is clarified and the recording density can be improved.
