摘要： A magnetic tape cartridge is compatible with a disk drive, which comprises a cartridge casing defining a thin space, a pair of tape reels onto which a magnetic tape is wound and means for defining a path for the magnetic tape along which a portion of the tape is exposed at a location at which data can be transferred between the tape and the disk drive head. The tape reels are associated with a drive mechanism for selectively driving one of the tape reels for driving the tape between the tape reels. The drive mechanism includes a center core driven to rotate by means of a turntable. The drive mechanism further includes a power train including reel drive gears designed to drive associated tape reels and an input gear drivingly connected to the center core so as to be driven by the turntable. The input gear is associated with means for selectively meshing the input gear to one of the reel drive gears depending upon the direction of rotation of the center core.

摘要： A disk-drive-compatible magnetic tape cartridge is provided with a tape guide for accurately positioning a magnetic tape in relation to a disk drive head. The tape guide includes a positioning section to be aligned with a rotation axis of a center core assembly when the center core assembly is chucked on a turntable of the disk drive. The tape guide also includes a guide section defining a tape run path across the disk drive head. The guide section is formed integrally with the section to be aligned with the center core assembly and so distanced from the latter as to accurately position the magnetic tape with respect to the disk drive head. Since the tape guide has the positioning section and guide section integrally, the distance therebetween can be maintained precisely constant. Therefore, tracking by the disk drive head becomes easier to allow high-density recording.
摘要翻译：磁盘驱动器兼容的磁带盒带有用于相对于磁盘驱动器头精确地定位磁带的磁带引导件。带导轨包括当中心芯组件卡在盘驱动器的转台上时与中心芯组件的旋转轴线对齐的定位部分。磁带引导件还包括引导部分，其定义穿过磁盘驱动器磁头的磁带运行路径。引导部分与要与中心芯组件对准的部分一体地形成，并且远离后者，以便将磁带相对于磁盘驱动器头精确定位。由于带引导件具有一体的定位部和引导部，因此能够将其间的距离精确地保持一定。因此，磁盘驱动器头的跟踪变得更容易允许高密度记录。

摘要： An auto-ejector incorporated in a disk recording and/or reproducing apparatus is driven by a disk driving motor and a head driving motor which are requisite for the apparatus. That is, the ejector is triggered under the power of the head driving motor, and a disk cartridge in which a disk is accommodated is ejected under the power of the disk driving motor. Thus, any device, such as an electromagnetic device, a motor or the like used only for the ejector is not needed.
