摘要:
Systems and methods for writing data to a disk under write disturbance conditions are provided. In one embodiment, a disk drive comprises a disk and a detection system configured to detect a write disturbance condition. The disk drive further comprises a controller configured to alternately operate in a normal mode and a write disturbance mode, wherein, the controller is configured to write data to data tracks on the disk in the normal mode and to write data to data tracks on the disk that are spaced farther apart in the write disturbance mode, and the controller is configured to switch from the normal mode to the write disturbance mode when the detection system detects the write disturbance condition.
