  • Patent number: 5739975
    Abstract: A memory storage module for storing and accessing information which includes a flat storage medium having an X-axis and a Y-axis. A plurality of read/write heads are coupled to a head array assembly which is capable of motion along the X-axis. The head array assembly positions the heads adjacent to the medium. An X-axis motor is coupled to the head array assembly and causes the heads to undergo reciprocating substantially linear motion along the X-axis of the medium. A Y-axis motor creates linear motion between the heads and the medium along the Y-axis of the medium. The heads are controlled to store or access information on the medium as the heads move across the X-axis of the medium. The Y-axis motor moves the heads from track to track along the Y-axis of the medium. The Y-axis motor can be connected to move either the medium or the head array assembly along the Y-axis.
