Abstract:
1. A disk drive, comprising: a disk for storing data; a head for reading data from the disk; an actuator for positioning the head; a first controller for controlling a movement of the actuator based on specific type of seek profile when operating in a specific seek mode to cause the actuator to perform a specific type of seek in which an acoustic output due to the movement of the actuator is less than 18 dB, the first controller having a plurality of available seek modes for carrying out each of one or more particular seek operations, the plurality of available seek modes including the specific seek mode; and a second controller for controlling the first controller such that the first controller operates in the specific seek mode when at least one of (i) the one or more particular seek operations are performed for ancillary operations, where the ancillary operations include at least one of internal housekeeping operations and operating system background operations, (ii) the one or more particular seek operations are related to internal commands generated by the second controller, and (iii) the second controller receives a command that selects the specific seek mode from among the plurality of available seek modes for performing the one or more particular seek operations.
