    摘要： A recording medium which realizes high sound quality and is playable on a conventional playback device has a recording layer provided with a double-layered structure having at least a first layer L1 and a second layer L2, an audio data program is recorded on the first layer in the first data format, which is the conventional format, and the audio data program is recorded on the second layer in a second, new data format. The audio data programs recorded on the first layer and on the second layer are the same program and can be produced using 1-bit DELTA SIGMA modulation having a high sampling rate as the new format, the DELTA SIGMA modulated signal being passed through successive decimation filters to form the lower sampling rate signal of the conventional format. The double-layered disk can be played back using a disk judging unit that detects the disk's table of contents and controls a laser beam focus of a pick up, an operating clock frequency, and the decoder for reading out the data recorded in pits formed on the disk.

    摘要： A cleaning device for cleaning magnetic head and photo pickup of a compact disc drive includes a playback-only disc medium received in a recording-enable disc cartridge. The disc medium has a Read-in TOC area for recording medium identification information to indicate a recording-enable disc medium, a User TOC area, a Recorded area, and a No-record area radially sequentially surrounding the Read-in TOC area. Information for managing records on the Recorded area is recorded in the User TOC area. A cleaning sheet for cleaning the magnetic head is attached to entire surface of the disc medium facing the magnetic head. The Recorded area is radially divided into three sub-areas. The inner sub-area has voice messages of "Cleaning starts" or for operating methods recorded therein, the middle sub-area has 30 minutes of silence and has a brush mounted thereto for cleaning the photo pickup, and the outer sub-area has a voice message of "Cleaning ends" recorded therein. The inner and the middle sub-areas are identified as a magnetic track No. 1 and the outer sub-area a magnetic track No. 2.

    摘要： A tape cassette is which a tape body is wound around a couple of tape reels rotatably supported to a cassette body. The cassette body has a first write inhibition mechanism provided at a place corresponding to the place where a write inhibition mechanism is provided in another tape cassette compatibly loaded in a recording/reproducing apparatus in which the tape cassette of the invention is loaded and a second write inhibition mechanism at a place not corresponding to the place where a write inhibition mechanism is provided in the other tape cassette, thereby making the first write inhibition mechanism always in a write-inhibition state. Even if a tape cassette on which an information signal is recorded in a recording format is loaded in a recording/reproducing apparatus for tape cassettes of a specific recording format which is one of different recording formats and is different from the recording format of the loaded tape cassette, the recording of information signals in the tape cassette is inhibited to protect the data already recorded.
