摘要： A motion pattern of an actuator supporting a head is monitored during/after a disc spin-up. The monitor's signal is configured to generate a digital indication of where the head was just before the spin-up. The digital indication is optionally a single-bit indicator that is used directly as a decision of whether to continue a start-up operation.
