Technical Examples
- A video recording/reproducing apparatus capable of discriminating commercial message portions even when a broadcasting mode is the same. A magnetic head records television broadcasting signals to a magnetic tape and reproduces the television broadcasting signals from this magnetic tape. When the television broadcasting signals are reduced by recording/reproducing apparatus, an audio-free portion detector detects audio-free portions from audio signals in the television broadcasting signals. Commercial message (CM) portion detector detects the commercial message portions in the television broadcasting signals by the time intervals among a plurality of audio-free portions detected by the audio-free portion detector, and a CM information memory circuit stores the information of the recording positions of the commercial message portions detected by this commercial message portion detector to the magnetic tape. When the television broadcasting signals are reproduced from the magnetic tape, reproduction is carried out while the commercial message portions are skipped, at the recording positions of the commercial message portions to the magnetic tape, on the basis of the information of the recording positions of the commercial message portions to the magnetic tape that are stored in the memory circuit.
- The present magnetic tape cartridge having a data storage medium connected to an integral cleaning tape section is designed to accommodate the length of cleaning tape in a manner that is compatible with existing tape drive systems. In particular, the hub on the supply reel in the single reel magnetic tape cartridge is dimensioned to accept the length of cleaning tape such that the radial position of the End Of Tape hole in the magnetic tape media occurs in the same position as that of existing single reel magnetic tape cartridges that are not equipped with the length of cleaning tape appended to the magnetic tape media. This enables the cleaning tape equipped magnetic tape cartridge to be compatible with existing tape drive systems.
- A magnetic-tape recording apparatus records digital data on a magnetic tape by a rotating head. It includes a first obtaining device for obtaining predetermined-unit video data; a second obtaining device for obtaining audio data corresponding to the predetermined-unit video data; a synthesizing device for synthesizing the predetermined-unit video data and the audio data corresponding to the predetermined-unit video data such that they are continuous on a track in the magnetic tape without any space disposed therebetween; and a sending device for sending data synthesized by the synthesizing device to the rotating head in order to record the data on the magnetic tape.
- When a magnetic tape material is slit into a plurality of magnetic tapes, projections are formed in edge portions of side surfaces of the magnetic tapes. The projections are removed by pressing cutting tools against the edge portions of the side surfaces of the magnetic tape while transporting the magnetic tape. Thus, product quality of the magnetic tape is improved.
- A magnetic recording/reproducing apparatus having a capability of allowing contents of records on a magnetic tape to be discriminatively identified and a capability for displaying closed caption includes a tape map memory for storing contents recorded on a tape and a tape map controller. As a manual input facility, a tape map button, a caption button, a play-back button, a stop button and others are provided. Upon loading of a tape undergone recording(s), the tape map button is pushed to display on a monitor screen tape map information concerning the contents of program(s) recorded on the loaded tape, temporal duration(s) of the program(s), and history of play-back of the tape.
