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.
