Abstract
Cartridge type magnetic recording and reproducing system comprises a magnetic transducer head which is arranged externally of a cartridge when the cartridge has been loaded, tape withdrawal means for drawing a length of tape from the cartridge for pressing it against the magnetic transducer head during recording and reproducing operations, a take-up motor for rotating one of two reel mounts to take-up tape slack into the cartridge when the press contact of the transducer head with the tape is released, and brake means for applying a brake force to the other reel mount.
Claims2
A magnetic recording and reproducing system of the type employing a tape cartridge having a magnetic tape wound therein on first and second reel hubs and including means for withdrawing a length of tape from the cartridge and pressing it against a magnetic transducer, wherein the improvement comprises:
- first and second rotatable reel mounts having said reel hubs mounted thereon,
- a take-up motor coupled to said first reel mount, said take-up motor rotating said first reel mount to wind the tape back into the cartridge when the pressure on said tape which holds it against said magnetic transducer is released and the tape becomes slack,
- braking means for applying a braking force to said second reel mount when said system is not in the recording, reproducing or fast-forward modes,
- a tape tension increase sensing member for sensing the increase in tape tension when said tape is wound back into said cartridge by said take-up motor, and
- stopping means for stopping rotation of said first reel mount by said take-up motor when said sensing member senses the increase of tape tension, whereby said tape is accommodated within said cartridge without any slack therein.
