Abstract
A disk drive includes a rotatable data storage disk, an interface, a transducer, a write buffer, an actuator, and a controller. The transducer is configured to read and write data on the disk. The interface is configured to receive data with associated write commands and a park signal. The write buffer is configured to temporarily store the data and associated write commands while the data waits to be written on the disk via the transducer. The actuator is configured to move the transducer between a parked position and tracks on a disk where data is read and written. The controller is configured to execute the buffered write commands by positioning the transducer relative to tracks on the disk while writing data from the write buffer to the disk, and is configured to respond to the park signal, which is indicative of an imminent transducer to disk contact condition, by moving the transducer to the park position without completing execution of the buffered write commands.
