Filed: 1986-10-08
Abstract: PURPOSE:To accurately position a data head to an object track without prolonging the settling time by adding a correction signal of a deviation stored before the settling by the servo head to an object servo track to the position signal. CONSTITUTION:In response to moving track number and direction, a CPU 217 outputs a reference speed signal to a D/A converter 216 and the position signal is a speed signal of a servo head via a differentiation circuit 209 and a phase switching circuit 210.
