摘要： A tape guide device having apertures formed in two tape-winding surfaces of non-rotatable curvature portions. A tape restriction is provided at a connecting portion of the tape guide device interconnecting the curvature portions. A flange is provided on one of the curvature portions for movement along an axis thereof to adjust the height thereof. The flange has an outer diameter greater than that of the one curvature portion. The curvature portions are integrated with each other. According this, an air film is generated between the tape and the tape-winding surfaces by discharging air from the apertures, thereby reducing the friction coefficient between the tape and the tape-winding surfaces to suppress the increase of tape tension. The tape is restricted to fluctuate in the direction of width. Further, the attitude and relative positioning between the curvature portions can be secured with high precision. As a result, the tape load during the tape running is reduced, thereby stabilizing the tape running and prolonging the lifetime of the tape.

摘要： As a method of increasing the storage capacity of a magnetic recording and reproducing apparatus for recording and reproducing information to and from a magnetic tape in a cartridge, there is a helical scan recording method in which the magnetic tape is diagonally wound around a drum which rotates a magnetic head. With an apparatus adapted to this method, the disposition of the cartridge and the take-up reel for taking up the magnetic tape on the same plane arises a necessity of considerably bending the magnetic tape at the drum portion and, accordingly, the magnetic tape is damaged. In order to prevent the damage of the foregoing type, the tape passage surface from the cartridge to the drum and the tape passage from the drum to the take-up reel are formed by an angle at which the direction in which the magnetic tape is moved is changed due to winding of the magnetic tape around the drum so that the magnetic tape is not bent excessively. A threading device capable of three-dimensionally controlling the position of the magnetic tape in accordance with a predetermined tape passage is provided for the apparatus structured as described above. The threading device is formed by a link mechanism to be moved along the locus of a cam groove so that the three-dimensional position control can be performed.

摘要： A recording/playback apparatus including a stationary drum on which a traveling magnetic tape is wound, a plurality of magnetic heads for recording and playing back data, a rotary portion which is rotated while carrying the heads thereon, a drive portion which drives the rotary portion, an air injection device which spouts air from the vicinities of the magnetic heads toward the magnetic tape in order to separate the tape from the heads, and a control device which controls the start and stop of the air spouting of the air injection device. In the standby mode of the apparatus, in which the rotary portion is rotated though the heads perform neither the recording nor the playback operation, the tape is separated from the heads, so that the heads are prevented from wearing away. As soon as the standby mode has ended, the tape is brought into contact with the heads, so that the recording or playback operation can be immediately started.

摘要： Disclosed in an arrangement to achieve satisfactory head contact by increasing contact face pressure at a head gap and to reduce the change in time of head contact performance in a double azimuth head. Heads in a portion in which a tape is slid are respectively constructed with each head having two different arcs with a radius of curvature R1 in a first area which includes a gap, and with a radius of curvature R2 in a second area which is adjacent to the first area. A transition portion P for transitioning an arc with the radius of curvature R1 and an arc with the radius of curvature R2 is located in the direction of its adjacent head based upon a contact point Q on R1 of a common tangent drawn from an arc forming a periphery of a rotating drum to a circle formed by R1. The relationship between the radiuses of curvature in two areas is set to R1>R2. As the area in which a tape is in contact can be reduced, contact face pressure by the tape on a gap can be increased, satisfactory head contact can be obtained and as a contact area with a tape is wide to some extent, a change in time of contact performance can be reduced.
