    摘要： A recording and playback device utilizing magnetic tape, such as a tape cassette, as a recording medium includes a magnetic head arranged to contact one side of the magnetic tape and a stabilizer arranged positioned directly opposed the magnetic head corresponding to the opposite side of the magnetic tape such that the magnetic tape move along a path interposed between the stabilizer and the magnetic head. The stabilizer includes a tape slider surface in contact with the side of the tape opposite the magnetic head contacting side. Further, the tape slider surface of the stabilizer may be formed with a recessed portion and tape surface scraper portions. According to this structure vibration of the magnetic tape in the vicinity of the magnetic head is greatly reduced such that a head servo for control of the magnetic head may accurately position the magnetic head even in devices utilizing a very small track pitch. Also read/write error, tape dropout, and the like, due to foreign matter entering the tape path, is reliably prevented. Further, space between the magnetic tape and the head is reduced and contact pressure between the head and the tape is maintained to optimize recording and or playback operations between the head and the magnetic tape.

    摘要： The rotation of a drive roll is detected using an rpm detection enabling element provided on the drive roll in order to control the driving device and reduce data error and loss of storage capacity. A cover member 3 and a base plate 4 make up a main cartridge member 2 within which a pair of tape reels 8, 9 are accommodated. A magnetic tape 7, placed around the tape reels 8 and 9, is driven by a drive roll 13 the outer periphery of which is partially exposed via an opening 21 formed in the front surface of the cover member 3. A capstan roll 46 of a driving device 40 is in surface contact with the driving roll 13 for transmitting its rotation to the drive roll. A rpm detection enabling element 34 is provided on the drive roll 13 and is detected through a detection window 35 provided in the cover member 3. The rotational speed difference between the drive roll and the capstan roll is used to detect slip therebetween.

    摘要： A tape cassette comprises a supply and a take-up reel on which tape is wound, a cassette casing for rotatably enclosing the reels therein, a plurality of tape guide pins, each being press-fitted through the inner wall of the casing, for defining a tape path for the tape travelling between the pair of reels. The press-fit section of each guide pin is formed in a predetermined taper in such a manner as to gradually decrease its outer diameter towards its end. The straight press-fit section of the guide pin is formed in such a manner as to include a predetermined geometry of chamfered circumference at its end. In a tape guide pin used in conjunction with a tape guide roller, grease having a predetermined viscosity coefficient is disposed between the associated pin and roller. An electrical insulating cover is provided for surrounding the exposed underside of the electrically conductive lower half of the casing.

    摘要： An improved tape cartridge with increased tape capacity comprises a cartidge housing including a base plate which has two portions. The two portions connect with each other to form at least one corner portion. At least one guide is located adjacent the one corner portion such that the tape web is held out of interference with the one corner portion. A driven roller is positioned such that a straight line drawn through the driven roller passes between axes of rotation of two tape packs mounted on the base plate and extends perpendicular with a straight line extending through the axes of rotation of the tape packs.

    摘要： A tape cartridge is comprised of first and second hubs which are aligned in tandem in a cartridge inserting direction to a recording and regenerating apparatus. A magnetic tape wound around the first and second hubs is driven by a drive belt through tape guides to be pressingly in contact with a magnetic head. The tape guides are arranged so that tape tension characteristics under a forward condition of the tape cartridge become the generally same as those under a reverse condition.
