Abstract: A container for a memory card and the process by which the container is manufactured. The container comprises chiefly two stamped steel covers, (an upper and a lower cover half), each secured to a plastic frame element. The cover halves are secured by extended fingers which wrap around the plastic frame. This provides a double layer of metal at the perimeter of the frame. The two cover halves are situated so as to encapsulate the subject PCB and to affix it in its proper position. The two cover halves are then welded together using sonic welding on the plastic frame. The frame has been designed to meet all PCMCIA standards, including polarizing keys and grounding points.

Abstract: A method and apparatus for improving the average throughput of rotating magnetic or optical data storage systems. Multiple-sector data along a given track 120 is transferred between the rotating media and the disk controller circuitry essentially within a single rotation as each desired sector passes under the read/write head, even if out of order. The method is implemented in the hardware and/or firmware of a disk controller.
