Fixed disc drive cartridge and playback device

A data storage system comprising:

• a removable sealed fixed disc drive cartridge, including:
• a sealed enclosure;
• at least one rotatable fixed disc;
• at least one head disposed proximate the disc to at least read data from the disc during disc rotation;
• a first actuator operably coupled to the at least one head, and adapted to move the at least one head relative to the at least one disc;
• a first connector operably coupled to the at least one head and to the first actuator;
• a playback device including:
• read/write circuitry;
• an at least one input port operably coupled to a host device to receive and provide input data;
• an output port operably coupled to the read/write circuitry to provide data read from the at least one disc;
• a controller operably coupled to the input port and the read/write circuitry;
• a motor driver operably coupled to the controller;
• and
• a second connector operably coupled to the read/write circuitry, and to the motor driver, the second connector being operably engageable with the first connector to thereby operably couple the read/write circuitry to the at least one head and to operably couple the motor driver to the first actuator;
• a spindle motor operably coupled to the motor driver and operably coupled to the at least one fixed-disc to rotate the at least one fixed disc;
• a multiplexer electrically interposed between the input port and the controller, and wherein the multiplexer is adapted to provide a selected one of a plurality of data streams received from the input port to the controller;
• and
• preamp circuitry disposed within the removable, sealed fixed disc drive cartridge operably coupleable to the at least one head and to the read/write circuitry.
