发明名称 Magnetic tape cartridge transducing apparatus and method
摘要 An apparatus and method are provided for transducing information with respect to magnetic tape supplied and supported within a magazine or cartridge. In one form, the tape in the magazine extends from a supply reel to a take-up reel and a free length thereof between the supply and take-up reel is exposed to the exterior of the magazine as it is driven past a semi-cylindrical supporting surface forming part of the magazine. Either by movement of the magazine and/or a drum-shaped support for a number of magnetic transducers, into engagement with each other, the tape is made to conform to the semi-cylindrical surface support of the magazine and to the cylindrically shaped surface of the drum supporting the transducers. Thereafter the tape is driven from the supply to the take-up reel against or closely adjacent to the drum-shaped transducer support in a manner such that one or more magnetic heads supported by the drum scan transverse tracks of the magnetic tape. In so doing, high speed magnetic recording and/or reproduction of information, such as video information generated in the megahertz frequency range may be recorded along the transverse tracks of the tape without the need for driving the tape at extremely high speeds.
