Read error recovery method and apparatus

The present invention provides a method and apparatus for recovering data in a disk drive following a read error. At least a portion of the actuator arm tip is heated. Thermal expansion reduces the read-head-to-disk spacing, increasing the likelihood of success when a re-read of the data is attempted. In one approach, a heater is operatively coupled to the tip. In one aspect, a write head is provided with write current in order to heat the tip. Data which may be modified or overwritten when providing write current to the write head is preferably read and buffered prior to the write operation, for later re-writing to the disk.
