DESCRIPTION:
BRIEF SUMMARY
TECHNICAL FIELD
This invention relates to a recording medium device comprising of a disc-shaped recording medium, such as a tape-shaped recording medium, e.g., a magnetic tape having information signals recorded thereon, or a disc-shaped recording medium, e.g., an optical disc or a magneto-optical disc, enclosed in a cartridge main body. More particularly, it relates to a recording medium device having a contact terminal for electrically connecting electrical components, such as a memory elements, housed within the cartridge main body, to the recording and/or reproducing apparatus when the device is loaded on a recording and/or reproducing apparatus configured for recording and/or reproducing information signals.
BACKGROUND ART
Up to now, a tape cartridge is employed as a recording medium for a recording and/or reproducing apparatus for a tape recorder or a video tape recorder. This tape cartridge has a cartridge main body formed by abutting a rectangular upper cartridge half and a rectangular lower cartridge half. A pair of tape reels are rotatably accommodated within the cartridge main body and a magnetic tape for recording information signals, such as audio or picture signals, is placed around these tape reels. The magnetic tape is reeled out from one of the tape reels on the tape supply side to outside of the cartridge main body so as to travel along the front side of the cartridge main body for being taken up by the opposite side tape reel on the tape take-up side.
On the front side of the cartridge main body, within which runs a magnetic tape reeled out from one of the tape reels and taken out on the opposite tape reel, there is formed a loading recess into which part of a loading mechanism adapted for loading a magnetic tape in a tape running path within the recording and/or reproducing apparatus is introduced.
The cartridge main body is fitted with a front cover for opening or closing the front side of the cartridge main body formed with the loading recess along which runs the magnetic tape reeled out from the tape reel. The front cover is mounted with a rotational bias produced by a spring member in a direction of closing the front side of the cartridge main body. In the non-use state of not being fitted on the recording and/or reproducing apparatus, the front cover covers the magnetic tape extended on the front side of the cartridge main body for protecting the magnetic tape. When the tape cartridge is loaded on the recording and/or reproducing apparatus, the front cover is turned by a lid opening member mounted in the recording and/or reproducing apparatus for opening the front side of the cartridge main body for enabling loading of the magnetic tape in the tape running path.
With this sort of the tape cartridge, the magnetic tape may differ in design statements even though the outer shape of the cartridge main body is the same. For example, in the case of a tape cartridges housing a magnetic tape having a tape width of 8 mm, some of them are used as a recording medium for a drive device as an external recording device for an information processing apparatus, such as a computer, for exclusively recording data signals as digital signals, while others are used as a recording media for video tape recorders for exclusively recording picture or audio signals. The tape cartridge employed for recording data signals and the tape cartridge employed for recording picture or audio signals are designed so that a magnetic tape having a tape width of 8 mm is housed within the cartridge main body having a unified size and a substantially common outer shape. Thus it is extremely difficult to distinguish a tape cartridge employed for recording data signals and a tape cartridge employed for recording picture and audio signals.
Meanwhile, the tape cartridge employed for recording the data signals and the tape cartridge employed for recording the picture and audio signals differ with respect to the design statements of the recording media. The tape cartridge employed for recording the data signals has a storage
