Multiplexed communication in a storage device

A storage device, comprising:

• a storage medium;
• a read/write head comprising a read sensor and a write element;
• preamplifier circuitry, electrically connected to the read/write head, wherein the preamplifier circuitry comprises read circuitry and write circuitry, wherein the read circuitry is configured to drive the read sensor to read data from the storage medium and to process the read data, and wherein the write circuitry is configured to drive the write element to write data to the storage medium;
• recording channel circuitry comprising read data circuitry and write data circuitry, wherein the read data circuitry is configured to decode read data that is received from the preamplifier circuitry, and wherein the write data circuitry is configured to encode write data that is to be written to the storage medium;
• an analog bus comprising a plurality of analog lines connecting the recording channel circuitry to the preamplifier circuitry;
• and
• multiplexing circuitry configured to control transmission of read and write information signals between the recording channel circuitry and the preamplifier circuitry over one or more of the plurality of analog lines,
• wherein the analog bus includes a first analog line, and wherein the multiplexing circuitry is configured to selectively transmit one of (i) write data over the first analog line from the recording channel circuitry to the preamplifier circuitry during a write operation, and (ii) first read data over the first analog line from the preamplifier circuitry to the recording channel circuitry during a read operation.
