Abstract:
A disk drive that monitors changes in flying height is disclosed. In one embodiment, the disk drive includes a disk for storing information and an air bearing slider with a transducer that includes a write element for writing information to the disk during a write operation and a magneto-resistive (MR) read element for reading information from the disk during a read operation. The MR read element generates a readback signal during the write operation that includes a thermally induced signal caused by thermal changes in the MR read element and a magnetically induced signal caused by magnetic flux applied by the write element to the MR read element. The thermally induced signal has a relatively low frequency content and the magnetically induced signal has a relatively high frequency content. The disk drive also includes a low pass filter for receiving the readback signal and isolating the thermally induced signal from the magnetically induced signal, a threshold detector for receiving the thermally induced signal from the filter and generating a high fly write detection signal when the thermally induced signal exceeds a threshold value, and a controller for modifying the write operation in response to the high fly write detection signal.

Abstract:
A disk drive includes a slider assembly and a controller that directs current to the slider assembly to dynamically adjust the head-to-disk spacing. In one embodiment, the slider assembly includes a write element having a first end, a second end and an intermediate section, a conductor that is connected to the intermediate section. In this embodiment, the controller directs electrical current through the conductor to heat the write element without writing data to a storage disk. The electrical current can be directed through the conductor at any time prior to data transfer or during data transfer. Heating the write element causes a deformation of the slider assembly to decrease the head-to-disk spacing. In another embodiment, the slider assembly includes a separate slider deformer. Electrical current is selectively directed to the slider deformer to cause a deformation of the slider assembly to obtain a desired head-to-disk spacing.
