ABSTRACT:
A data storage system that uses a magnetic head assembly having a write head and a read head mounted on a slider to write on and read from a disk. A portion of the coil of the write head is used as a wear sensor for detecting wear on the surface of the slider. A head IC monitors the coil voltage and, when it goes lower than a reference voltage, detects the occurrence of a fault in the write head due to excessive wear on the slider surface. In response to the detection of the fault in the write head by the head IC, a control driver prohibits a write operation and saves data already recorded on the disk.
