2. Description of the Related Art In recent years, along with the progress of digital technology and television technology, the performance of VTRs has been improved by digitization and high-definition. Furthermore, the improved VTRs have been used as storage devices for computers. Diversification of recording and reproducing systems is progressing, such as the development of applied recording and reproducing systems. In such a diversification of systems, focusing on the application of the cassette cartridge that accommodates the tape as the recording medium, a cassette cartridge having the same outer shape as the cassette cartridge used in the conventional system is used in the new system. It may also be used as a cassette cartridge. In this case, even if the cassette cartridge used in the conventional system and the new system have the same outer shape, if the tape as the recording medium has different specifications and the recording method is different, one system If the cassette cartridge for use is inserted into the recording / reproducing device of the other system by mistake, recording or reproduction cannot be performed. Therefore, it is necessary to prevent the cassette cartridge for one system from being inserted into the recording / reproducing apparatus of the other system.

As a conventional example of this erroneous insertion preventing means, for example, there is a means disclosed in Japanese Laid-Open Patent Publication No. 4-149880. In this disclosure means, as shown in FIG. 12, a cassette cartridge guide groove 31 for discrimination is provided on the bottom surface 30 of the cassette cartridge, and as shown in FIG. A section 36 is provided. Therefore,
When a cassette cartridge suitable for the system is inserted, the cassette cartridge guide groove 31 provided on the bottom surface 30 of the cassette cartridge has the cassette cartridge guide convex portion 3 of the cassette stage 35 provided on the recording / reproducing apparatus.
In order to avoid step 6, the cassette cartridge can be inserted to a predetermined position in the cassette stage 35. On the other hand, when a cassette cartridge that is not compatible with the system is inserted, the cassette cartridge guide convex portion 36 corresponding to the position of the cassette cartridge guide convex portion 36 of the cassette stage 35 provided in the recording / reproducing apparatus is avoided on the bottom surface of the cassette cartridge. Since there is no guide groove, the cassette cartridge guide protrusion 36 contacts the bottom surface of the cassette cartridge, and the cassette cartridge cannot be inserted into the cassette stage 35.
