Magnetic head moving velocity detector |
摘要 |
A detector for the moving velocity of a magnetic head of a magnetic disc memory device by electrically processing a position signal of the magnetic head, which includes a circuit for differentiating the position signal, means for rectifying the differentiating circuit, a circuit for sampling-hold of the rectified signal, a phase-shifter for delaying the position signal and means for generating a timing pulse signal to determine the timing for sampling, with the phase delaying characteristic of the transfer function of the differentiating circuit and the phase-shifting circuit being substantially coincided.
