Abstract
A method and apparatus for improving the data readability in a disk drive is described. The disk drive uses an error recovery mode in which the rotational speed of the motor is decreased below the normal operating speed and a rereading is performed. The reduced speed lowers the energy generated in collisions with a foreign object and the data error length is shortened allowing data to be read which cannot be read at the normal operating speed.
