摘要： A magnetic recording and reproducing apparatus utilizing a magnetic tape in a cassette, the tape being driven by reels and information data being recorded or reproduced on or from the magnetic tape. The apparatus includes a mechanism for pulling or storing the magnetic tape out of or in the cassette which mechanism includes a pair of guide rollers for restricting the running path of the magnetic tape, the guide rollers being movable between an unloading position and a loading position. A magnetic head, which can be a multi-track magnetic head having a plurality of magnetic heads, the number of which is defined to be smaller than the number of tracks standardized as a track format on the magnetic tape, records or reproduces information-data when the guide rollers are in their loading position and the head is allowed to vertically move each time the running direction of the magnetic tape is changed.

摘要： A magnetic recording/reproducing apparatus includes a guide roller which rotates as magnetic tape runs, and the running speed of the tape is detected on the basis of the rotation of the guide roller. The magnetic recording/reproducing apparatus further calculates a radius of a supply reel from the rotation of the guide roller and the rotation speed of the supply reel, calculates driving torque of the supply reel from the calculated result, and the supply reel is driven so that the tension of the magnetic tape is kept constant according to the calculated result.

摘要： Featured is a magnetic drum assembly including a rotary drum supporting a magnetic head for recording/reproducing information on a magnetic tape and a stationary drum secured to a base of a magnetic recording/reproducing device. In one aspect of the invention, the stationary drum is molded from a resin material together with a metal material partially embedded and partially exposed and being secured at the exposed part of the metal to the base of the magnetic recording/ reproducing device. In another aspect of the invention, the rotary drum is molded from a resin material together with a metal material partially embedded and partially exposed and the magnetic head is secured at the exposed part of the metal of the rotary drum. Such a drum assembly is advantageous in that it is capable of maintaining an initial accuracy of its sizes and shape without deterioration in its mechanical properties over time due to creep deformation and internal stress.
