IPC: G11B19/04
Filed: 1983-09-06
Abstract: PURPOSE:To decide easily the connecting state between a rotary driver and an object to be driven of a video master disk, etc. by revolving the rotary driver with a prescribed torque for a prescribed period of time and deciding said connecting state from the maximum number of revolutions of the rotary driver. CONSTITUTION:An object RA to be driven is connected to a rotary driver, and a motor driving signal Pm having the prescribed size (h) and time width tau is supplied to a motor M from a motor driving circuit MDA with the impulse of an impulse generator PSG. The revolving number of the rotor obtained at that time point is converted into the voltage corresponding to the number of revolutions by a tachogenerator TG. The level of said voltage is low and high when the connecting state is satisfactory and unsatisfactory between the rotary driver and the object to be driven respectively. Therefore a signal is delivered from a comparator COMP only when the connecting state is unsatisfactory by setting the threshold voltage of the COMP at a level slightly higher than the maximum level of said voltage delivered from a detecting circuit MLD while the connecting state is satisfactory.
