  • Disc storage subsystem having improved reliability
    Patent number: 6831831
    Abstract: A disc storage subsystem includes a housing, at least one disc drive assembly received in a front portion of the housing, first and second controllers, and an intermediate electronic component. The disc drive assembly includes a carrier supporting a disc drive having an Advanced Technology Architecture (ATA) data interface. The first and second controllers each include a data port corresponding to the disc drive. The intermediate electronic includes multiplexing electronics having first and second data communication paths. The first data communication path provides electronic communication between the data port of the first controller and the data interface of the disc drive. The second data communication path provides electronic communication between the data port of the second controller and the data interface of the disc drive. The multiplexing electronics selectively opens and closes the first and second data communication paths in response to at least one control signal.
