Abstract

PURPOSE: To obstruct the rise of resonance vibration in the case when a head approaches to a location "O", by mounting a vibration preventive circuit produced so as to interrupt a blind sector of an amplifier.
CONSTITUTION: Oscillation signals generated by means of an oscillator 22 gradually decreasing a servo-clock 21 are fed to an amplifier 17, and a blind sector is interrupted by the signals, thus realizing a blind sector condition that interrupts at a period shorter than time necessary for the vibration of a servo-mechanism for positioning. A keying circuit 23 of signals from the oscillator 22 acts by detecting output voltage Eout in reaching to the blind sector. The blind sector is intermittently operated after a location of a head starts the deceleration of a target address location. The maximum reading signals are read from a track because the head is finally set to the center of a target address.
