  • Patent number: 6288993
    Abstract: A processing device is provided with a disk loading port and a cassette or cartridge loading port both formed in a substantially common top face or surface of the device so that a CD ROM as well as a cartridge ROM may be loaded from the top. A main circuit board, in which a CPU, data processors and other circuits are assembled, is positioned so as to substantially underlie both the disk and cartridge loading ports and generally arranged in a plane parallel to the common top face. The disk operating unit is formed of two portions, one having a lower surface on which the cartridge unit may be detachably mounted, and the other having an elevated portion in which the disk loading port as well as a disk driving mechanism is installed.

  • Patent number: 5544145
    Abstract: This invention provides a method of regenerating photographic data by combining a few external devices to a conventional video gaming device which is presently popular. In this method, photographic data stored in an optical disk are read out through a CD-ROM driver connected to the interface which is connectable with external memorizing devices and regenerated, in conformity with a system-controlling program and a CD-ROM controlling program each stored in a cassette ROM connected to the interface which is connectable with external memorizing devices, and a display data-preparing program enlarging said photographic data, and a utility program performing dealing and controlling of the referring, zooming and panning operations of said photographic data each stored in said cassette ROM or in another external memorizing device.

  • Patent number: 5224081
    Abstract: A search operation control apparatus in an optical disc reader searches a desired position on an optical disc which is controllably rotated at a constant linear velocity and has its information pits arranged in a segmental spiral, in response to a search command which includes information of the desired position. The apparatus has an optical pickup, an optical-pickup moving controller, and an optical-disc driving controller. The optical-pickup moving controller controllably moves the optical pickup from a current position to a desired position at high speed when it receives a search command. The optical-disc driving controller controllably drives the optical disc during an acceleration/deceleration control timing, and a free-run or constant-run time. During the high-speed translation of the optical pickup, spindle servocontrol to the optical disc is not executed, but the acceleration/deceleration control process and the free-run or constant-run control process are executed.

  • Patent number: 5222054
    Abstract: A seeking operation control apparatus in an optical disc reader reads track information stored in an optical disc with an optical pickup which is movable in the radial direction in order to seek a desired track. It includes a calculator for calculating track values, a jump driver, a jump controller, and a reading controller. The calculator calculates the number of tracks in the distance between the track onto which the optical pickup is positioned and a desired track based upon track information obtained by the optical pickup. The jump driver induces the optical pickup to jump one or more predetermined tracks. The jump controller controls the jump driver whereby it performs the track jump operation repeatedly as required to make the optical pickup jump the track value calculated by the calculator. The reading controller directs the optical pickup to read track information after the jump control operation is completed.
