摘要： A rotary optical head apparatus comprises a first rotary member carrying an objective lens and a second rotary member carrying an image rotator. The two rotary members are supported for rotation by means of a single common support shaft so that the axes of rotation of the two rotary members coincide with each other with a high degree of accuracy. Consequently, the linearity of a scanning line of a beam spot which is scanned on an optical magnetic tape is ensured with a high degree of accuracy.

摘要： A control circuit for controlling the position of a head in an optical tape recording/reproducing device having a rotary optical head controls the position of the head at the instant that it faces the tape based upon a desired head position derived from a preceding period in which it was facing the tape. A head position error signal is sampled and added to a sample head position signal during a period when the head is facing the tape and is held during the time the head is not facing the tape. The instant the head begins to face the tape once again, this desired value that has been held is applied to the head in order to reduce the pull-in time of the control circuit and provide more time for information recording/reproduction during the time the rotary optical head is facing the tape.

摘要： An optical recording method and an optical recording apparatus enable recording information on recording tracks substantially corresponding to ideal reference tracks, on an optical recording medium without preformatted tracks. The optical recording medium is scanned by a rotating optical scanning system using a scanning light beam emitted by an external light source to record information on the optical recording medium. Prior to recording the information on the optical recording medium, information recorded on a reference track recording medium provided with ideal reference tracks is reproduced in a tracking control mode to acquire tracking control data and the tracking control data is stored in a waveform memory. In recording information on the optical recording medium, the rotating optical scanning system is controlled on the basis of the previously stored tracking control data so that the scanning spot traces recording tracks corresponding to the ideal reference tracks.

摘要： A servo control circuit for an image rotator used in an optical tape recording apparatus that employs a rotary tape drum. Pairs of pulse generators and frequency generators are provided on the image rotator and on the tape drum, respectively. Initially, the pulse generators are used for servo control and, upon detecting a phase lock, servo control is subsequently switched over to be controlled by the frequency generators.

摘要： In response to a request from a playback apparatus over a network to play back content, a first recording/playback apparatus transmits data indicating content satisfying the request to the playback apparatus over the network. When selecting desired content from the transmitted data, the playback apparatus requests the first recording/playback apparatus to transmit data of the selected content to the playback apparatus over the network. When the data of the desired content is transmitted to the playback apparatus from the first recording/playback apparatus over the network in response to the request, the content being transmitted is played back via streaming. When the playback apparatus transmits data indicating the played back content and an address of a second recording/playback apparatus to the first recording/playback apparatus over the network, the first recording/playback apparatus transmits data of the played back content to the second recording/playback apparatus over the network in accordance with the address.
