摘要： A disc cartridge having a disc for recording information signals and a main cartridge body member for rotatably housing the disc. The disc cartridge is designed to be loaded on a recording and/or reproducing apparatus. The main cartridge body member has, on its one surface, a label area for bonding a display label indicating the recording contents of the information signals, while having, on its other surface, a spindle hole for rotating the disc by the recording and/or reproducing apparatus. The main cartridge body member has a design parameter discriminating hole extending along the back side opposite to the front side in the cartridge inserting direction. The recording capacity or design parameters of the disc housed within the main cartridge body member may be discriminated by detecting the design parameter discriminating hole.

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.
摘要翻译：利用诸如磁带盒之类的磁带作为记录介质的记录和重放装置包括一个设置成接触磁带一侧的磁头和一个与磁头相对的磁头相对置的稳定器磁带使得磁带沿着插入在稳定器和磁头之间的路径移动。稳定器包括与磁头接触侧相对的带的侧面接触的磁带滑块表面。此外，稳定器的带滑块表面可以形成有凹部和带表面刮刀部分。根据该结构，磁头附近的磁带的振动大大减小，使得用于控制磁头的磁头伺服器即使在利用非常小的磁道间距的装置中也可以精确地定位磁头。可靠地防止由于异物进入磁带路径而导致的读/写错误，磁带丢失等。此外，磁带和磁头之间的空间减小，并且保持磁头和磁带之间的接触压力，以优化磁头和磁带之间的记录和/或重放操作。

摘要： A recording/reproducing apparatus in which recording/reproducing characteristics for the magnetic tape may be stabilized and data errors may be reliably prevented form occurrence. The recording/reproducing apparatus has a magnetic head 81 in which a pair of magnetic core halves 83A, 83B of a magnetic material are abutted to each other via a gap material g to form a magnetic core. Magnetic tape guide units 82A, 82B are provided in the vicinity of the magnetic head 81. The magnetic tape guide units 82A, 82B are formed with magnetic tape suction openings 82b, 82b closed by a magnetic tape 88 adapted for having a sliding contact with the tape slide surface 82a. The magnetic tape suction openings 82b, 82b suck the magnetic tape 88 running on the tape slide surfaces 82a, 82a of the magnetic tape guide units 82A, 82B.
