    摘要： A magnetic head device has a base portion 3, and a magnetic head element 4 protuberantly formed on a major surface of the base portion 3 and having a magnetic core with a magnetic gap g. A magnetic tape controller 5 surrounding the magnetic head element 4 and contacted with a magnetic tape 2 is provided on a major surface of the base portion 3. The magnetic tape controller has a magnetic tape attracting aperture 5A for exposing a magnetic tape slide surface 4B of the magnetic head element 4 to outside. The recording/reproducing characteristics for the magnetic tape are stabilized and data errors are prevented from occurring.

    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： 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 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： A tape cartridge for housing magnetic tape includes first and second tape guide portions including upper and lower flanges provided thereon for guiding tape along a predetermined tape path according to rotation of supply and take-up reels of the tape cartridge. The tape is disposed such that an upper edge thereof contacts an inner side of an upper flange of the first tape guide and an inner side of the lower flange of the second tape guide. A width dimension between these two inner sides of the flanges being substantially equal to the width of the tape. This may be effected by mounting the first and second tape guide portions at different heights on a base plate of the cartridge. According to this, it is possible to substantially reduce `offtracking` of tape running in said cartridge.
