An operation starting time T0 from a generation time of a tap change command signal Vt to the start time of operation and an operation requiring time T1 from the start time to the finish time of the switch 8 are measured. If the operation start time T0 is over a given level, the switching operation is judged defective, and if the operation requiring time T1 is over a given level, the result is judged that the switching speed becomes defective because its speed is low.  If the operation requiring time T1 is over a ceiling value larger than the given level, the result is judged that a defect of halfway stoppage in changing is caused.

Title: Disk clamping device
Inventor: YAMAMOTO KAZUTO
IPC: G11B19/22
Filed: 1987-12-28
Abstract: PURPOSE:To protect a magnetic disk device when a foreign matter is inserted, and to easily take off the foreign matter by controlling the stop of a spindle motor and a clamping motor based on the output of the logical sum of a timer and a clamping detecting switch. CONSTITUTION:When the foreign matter is inserted into a magnetic disk device, a disk in-switch 1 is turned on, a spindle motor 7 is rotated, a clamping motor 8 is also rotated, and a clamping action is once started. However, since the foreign matter does not have a center hole, a center cone collides with a part of the foreign matter, and the clamping action is stopped. That is, after the passage of a T time, a timer 2 sends a control signal through an OR circuit 4 to a clamping motor control circuit 6, and it stops the clamping motor 8 and the spindle motor 7. Thereafter, the timer 2 sends the control signal to a regular/reverse rotation switching circuit 9, and reversely rotates the clamping motor 8. Thus, a colliding-connecting condition with the foreign matter can be canceled.
