摘要： A magnetic tape cartridge having at least one tape pack contains liners which form guide channels for the outer turns of the pack and/or for magnetic tape being wound or unwound and also include resilient sections for locating the tape pack and/or the winding hub in the central plane of the cartridge. The magnetic tape cartridge of the invention can be used with particular advantage as a compact cassette beacause of its outstanding reliability in operation.

摘要： The invention relates to magnetic tape cartridges in general in which between the tape packs and the upper and lower cartridge walls liners are provided which have regions that resiliently guide the tape packs and/or the magnetic tape. By means of specifically shaped regions of the liners, guide channels for the outer turns of the tape pack and/or for the winding or unwinding magnetic tape are formed according to the invention. By virtue of particular spatial arrangements of these guide channels, slipping and folding of the turns of tape already wound is avoided and the magnetic tape is maintained in the correct position as it leaves and joins the packs, irrespective of the type of bearing means used for the tape winding reels and irrespective of the shape of the tape packs, so that disturbances in operation are avoided and the tape is correctly positioned relative to the scanning means. Cartridges according to the invention may be employed advantageously in the recording and reproduction of audio and other signals.
摘要翻译：本发明涉及一般的磁带盒，其中带盒和上，下盒壁衬套之间设置有具有弹性引导带包和/或磁带的区域。通过衬套的特定形状的区域，根据本发明形成用于带包的外圈和/或缠绕或退绕磁带的引导通道。凭借这些引导通道的特定的空间布置，避免了已经缠绕的磁带的折叠和折叠，并且当磁带离开并连接包装时，磁带被保持在正确的位置，而不管用于磁带卷绕卷轴并且与带包的形状无关，从而避免了操作中的干扰并且相对于扫描装置正确定位带。根据本发明的墨盒可有利地用于记录和再现音频和其它信号。

摘要： The invention relates to a hub for magnetic tape cassettes, especially compact cassettes, and to magnetic tape cassettes possessing such hubs. In a first embodiment, spring means are provided on the inner periphery of the hub and exert radial pressures on the drive spindle, the spring means consisting, for example, of sprung teeth. In a further embodiment, the teeth have a spring rate of from about 1 P/mm to 40 P/mm. In another embodiment, the hub consists of an inner part and an outer part which can be coupled to one another and between which there is some play after coupling. A large number of specific examples of hubs are given to show possible shapes and arrangements of the teeth, and to show the types of material that can be used. In an advantageous embodiment, the inner part of the two-part hub can also be made a part of the drive spindle on the recorder, which inner part can be coupled with the outer part when the drive spindle enters the cassette.
摘要翻译：本发明涉及一种用于磁带盒，特别是小型盒式磁带的集线器以及具有这种集线器的磁带盒。在第一实施例中，弹簧装置设置在轮毂的内周上并在驱动轴上施加径向压力，弹簧装置例如由弹簧齿组成。在另一个实施例中，齿具有约1P / mm至40P / mm的弹簧刚度。在另一个实施例中，轮毂由内部部分和外部部分组成，该部分和外部部分可以彼此连接，并且在连接之后有一些间隙。轮毂的大量具体示例被给出以示出齿的可能形状和布置，并且示出可以使用的材料的类型。在有利的实施例中，两部分轮毂的内部部分也可以被制成记录器上的驱动主轴的一部分，当驱动主轴进入盒时，该内部部分可以与外部部分联接。

摘要： A process for the production of magnetic recording media by applying a magnetic layer, which consists essentially of magnetic material finely dispersed in organic polymers, to one side of a flexible base, and applying a non-magnetizable backing coating which is free of inorganic solids to that side of the base which is opposite the magnetic layer, wherein the backing coating consists of two or more polymers which are incompatible with one another and have precipitated from a solvent mixture, and magnetic recording media produced by this process.

摘要： A tape cassette, in particular a video cassette, comprises two flanged reels and, between the flanges of each reel, a spring member as a biassing means to prevent the tape from slipping off the roll or folding over. The spring members can be attached to the side walls or rear wall of the housing, and their free ends constantly bear against the peripheries of the tape rolls. In specific embodiment the spring member advantageously includes the braking spring for a reel-braking device. By using a conductive material on one or both sides of the spring member and appropriately arranging the spring member relative to a tape guide element or to an element grounded on the tape recorder, it is possible to directly prevent tape loop formation, which is a cause of tape slippage and folding-over. Moreover, tape winding and unwinding are improved.

摘要： Guide elements for magnetic tapes wound or to be wound in the form of packs on flangeless spools, the guide elements being movable in the plane of rotation of the packs. At least part of the guide elements is located between the pack and the outermost winding and thus constantly guides the tape as it is wound or unwound, resulting in optimal tape guidance and consequently in a stable and accurate winding on the spool.
