Abstract:
1. In a data storage device having one or more media surfaces, a corresponding number of at least read devices, a spindle motor for moving the one or more media surfaces, an actuator for moving the at least read devices relative to the one or more media surfaces, a read device preamplifier, coupled to the at least read devices, a servo control coupled to the actuator, for driving the actuator in response to control signals, an integrated data storage device controller integrated circuit comprising: a host interface for interfacing with a host computer; at least one internal communications and control bus, for transferring stored data and control data to and from elements within the integrated data storage device controller and interconnected with the host interface to transfer stored data and control data to and from the integrated data storage device controller; a read device data processor, coupled to the read device preamplifier and the at least one internal communications and control bus, for receiving and processing read device data from the read device preamplifier; a motion control servo logic, coupled to the at least one internal communications and control bus, and to the servo control, for generating control signals for driving the servo control; a disc controller, coupled to the at least one internal communications bus, for transferring stored data to the host interface; and a microcontroller, coupled to the at least one internal communications bus, for generating control data to control devices within the integrated data storage device controller integrated circuit.
