  • Patent number: 7929244
    Abstract: A magnetic tape recording/reproducing apparatus is disclosed that selectively loads a first tape cassette accommodating a first magnetic tape or a second tape cassette accommodating a second magnetic tape having a width greater than the width of the first tape. The apparatus includes a rotating drum unit including a lower stationary drum and an upper rotating drum, and a loading mechanism that, if the first tape cassette is loaded, pulls the first magnetic tape out of the first tape cassette and winds it onto the rotating drum unit through a first winding angle so as to form a first tape path and, if the second tape cassette is loaded, pulls the second magnetic tape out of the second tape cassette and winds it onto the rotating drum unit through a second winding angle greater than the first winding angle so as to form a second tape path.

  • Patent number: 7379263
    Abstract: A magnetic recording/reproducing apparatus is disclosed that is arranged to receive a tape cassette accommodating a tape recording medium that is selectively loaded thereto, the loaded tape cassette being selected from plural different types of tape cassettes of different sizes. The apparatus includes a rotating drum unit having a rotating head, and plural loading poles that are configured to pull the tape recording medium of the loaded tape cassette out of the loaded tape cassette, wind the tape recording medium of the loaded tape cassette around the rotating drum unit, and form a tape path. The loading poles include a common loading pole that is used when any one of the different types of tape cassettes is loaded, and an individual loading pole that is used when a predetermined type of tape cassette of the different types of tape cassettes is loaded.
