Abstract: A method is provided to enable communication between a controller and a preamplifier in a storage device. For example, the method includes implementing a serial port which is configured to transmit digital signals between the controller and the preamplifier over a single bidirectional serial data line. The serial port is controlled to selectively transmit digital signals over the bidirectional serial data line in either a first direction from the controller to the preamplifier or a second direction from the preamplifier to the controller.

Abstract: A method is provided, for example, to implement multiplexed communication on an analog bus between a recording channel and a preamplifier in a storage device. A first input of read data circuitry within the recording channel is switchably connected to a first analog line of the analog bus to receive read data transmitted from the preamplifier to the recording channel over the first analog line during a read operation. In addition, a write data output of write data circuitry within the recording channel is switchably connected to the first analog line of the analog bus to transmit write data from the recording channel to the preamplifier over the first analog line during a write operation.

Abstract: A method is provided, for example, to implement multiplexed communication between a controller and a preamplifier in a storage device. For example, multiplexed communication is implemented by controlling a bidirectional serial data line of a digital bus to selectively transmit digital signals in either a first direction from the controller to the preamplifier or a second direction from the preamplifier to the controller, in response to a direction control signal, and concurrently transmitting a synchronous clock signal over a clock signal line of the digital bus from the controller to the preamplifier to synchronize transfer and processing of the digital signals transmitted on the bidirectional serial data line of the digital bus. The direction control signal is transmitted from the controller to the preamplifier on one of the bidirectional serial data line and the clock signal line of the digital bus.
