  • Patent number: 8073312
    Abstract: A recording condition and a dubbing condition of a desired program that is to be broadcast are designated by using a remote controller. These conditions are stored in the information storage unit. In accordance with the recording condition, a controller permits a tuner to receive a program for which unattended recording is designated, and to record the program on an HDD. When a DVD is set in a dubbing unit and the dubbing operation is instructed by using the remote controller, a recorded program for which a dubbing condition stored in the information storage unit is applied can be dubbed. Then, the information for this program is displayed on a monitor so as to confirm the program and the dubbing condition, and to examine or correct CM skip if the CM skip is included in the dubbing condition. Thereafter, the dubbing operation is performed.

  • Patent number: 6948179
    Abstract: A disk cartridge is provided in which if the width of the disk cartridge is W1 and the outside diameter of the disk is D1, then W1 is about the same as D1. Inside the disk cartridge is a disk space in which the disk can rotate. A movement restricting portion restricts movement of the disk in the direction parallel with a disk surface. A cutout that extends through into the disk space is provided in part of a surface forming the width of the disk cartridge. A protrusion is provided in the surface adjacent to the surface in which the cutout is provided and at a position near the cutout.

  • Publication number: 20050030866
    Abstract: To quickly display catalog information on thumbnails and other data stored on an optical disk, management information or catalog information recorded on the optical disk and identification information and history information on the optical disk are stored on a storage other than the optical disk. If, when the optical disk is inserted, the history information or the identification information read from the optical disk matches the history information or the identification information stored on the storage, the management information or the catalog information stored on the storage that has a higher access speed is read and the information is used immediately.

  • Patent number: 5812340
    Abstract: A magnetic tape recording and reproducing plug-in unit including a case with a front plate having an insertion opening through which a magnetic tape cassette is inserted, a bottom plate, a top plate, and a pair of side plates each formed with a pair of guide slots arranged for guiding the cassette to a loading position. The slide plates are attached to the side plates so as to be slidable within the case, each slide plate formed with a pair of cam slots arranged for moving the cassette to the loading position. A cassette holder is disposed inside the pair of slide plates for holding the cassette and has pins extending through the cam slots into the guide slots of the side plates. A recording and reproducing device is mounted on the bottom plate. A driving device drives the slide plates. An electronic circuit is disposed at the rear of the recording and reproducing device.

  • Patent number: 5278707
    Abstract: A plurality of tape guides are moved to wind a magnetic tape on a rotatable cylinder when the magnetic tape is to be loaded. An auxiliary guide mounted on a chassis of a magnetic recording and/or reproducing apparatus in position is made to touch the magnetic tape during a period for which the magnetic tape is being loaded, but it does not touch the magnetic tape when the magnetic tape has been loaded. The auxiliary guide can be protruded toward the magnetic tape from between the tape guides moving to touch the magnetic tape during the period for which the magnetic tape is being loaded so that the magnetic tape can be kept to a predetermined span.

  • Patent number: 5016125
    Abstract: A helical scanning type of magnetic recording/reproducing apparatus in which a first entrance-side tape height regulation guide is disposed in a level higher than a center of a plane of rotation of magnetic heads mounted on a rotary drum assembly when the magnetic tape is loaded on the rotary drum assembly, and a first exit-side tape height regulation guide is disposed in a level lower than the center of the plane of rotation of the magnetic heads. The rotary drum assembly is disposed in a higher position such that its upper end is in the same level as an upper end of a lid of a tape cassette. The cassette is disposed at a lever lower than that of the first exit-side tape height regulation guide. The first entrance-side and the first exit-side tape height regulation guides are driven by a loading ring inclined towards the cassette so as to move while engaging with the magnetic tape during loading or unloading.
