Abstract: According to one embodiment, a disk drive includes a measuring module, a flying height controller, a detection module, and a controller. The measuring module is configured to measure the flying height that the head has with respect to the disk. The flying height controller is configured to control the head flying height in accordance with a value preset for the head flying height. The detection module is configured to detect the values representing the environmental elements of the head. The controller is configured to adjust the preset value in accordance with the flying height measured by the measuring module and values detected by the detection module if environmental changes are detected from the environmental element values output from the detection module.

Abstract: According to one embodiment, a disk drive is provided, which starts reading data at the head thereof, when a sync mark is detected. The disk drive has a read channel that generates a forced SM detection signal if the sync mark cannot be detected because of the occurrence of TA. The read channel starts generating the forced SM detection signal at the end position of a preamble, which is equivalent to the position of the sync mark.
