  • Patent number: 5455926
    Abstract: An optical disk storage system emulates a magnetic tape subsystem by virtual addressing of data recorded on write once optical disk media having a predetermined group of available sectors for rewriting a disk ID, a predetermined plurality of bands of available sectors for rewriting a virtual tape directory to virtual tape VSNs, and, available sectors for rewriting virtual tape maps and rewriting user records, the tape maps have data portions for simulating tape marks and interblock gap and for addressing blocks of data within the virtual tapes, the virtual tape directory has pointers for pointing to tape maps, and the system rewrites the tape directory, tape maps and user records so as to function as a rewritable magnetic tape.

  • Patent number: 5438674
    Abstract: An optical disk system emulating a 3480 magnetic tape subsystem having one or more magnetic tape drives, includes a VMEGate channel attached processor for receiving CCW tape commands, a SCSI board for controlling SCSI optical disk drives, a serial I/O board for controlling jukebox optical disk media handlers for automatically robotically loading and unloading optical disks containing virtual tape data into the optical disk drives, a cache RAM for buffering data between the channel and the optical disk drives, operator consoles for emulating the 3480 magnetic tape subsystem control panels, an SBC computer and VME bus for central control of the system, and floppy and hard disk drives for storing emulation SBC programs and disk directories, to enable the system to exhibit an organization of virtual tape data into a system of pointers and user records of the virtual tapes, a reallocatable mapping between magnetic tape drives and the optical disk drives, disk directories cross referencing virtual tapes VSNs to opt

  • Patent number: 5276865
    Abstract: A backup device and method for automatically backing up the memory of a computer. The device is installed inline between the electrical outlet and the computer, and also inline between the keyboard and computer. The user initiates a backup/powerdown routine by moving a switch on the device to "off". This in turn disables the keyboard and sends a keycode string from the device to the computer to begin execution of a previously specified backup routine. When the backup is completed, the device de-energizes a relay in the power line to the computer which powers down the computer.
