摘要： A tape head assembly for high-speed and high-density multi-channel read-while-writing (RWW) operation comprises two modules bonded together. The modules are initially formed on an integral unit and gapped in pair, to produce a good reference surface, which insures that the finished head assembly will meet tight azimuth and gap tolerances. The unit is then machined to two separate the modules. Further processing involves individually machining the head surface of each module to achieve desired contours. The machined modules are tested and brought together in the positional arrangement required to form the final head assembly. In disclosed embodiments, the overall contour enables the assembly to skive air and debris off a surface of the magnetic tape before passage of the tape over the transducers. The contour allows the tape to fly over outriggers, but contacts regions at or around the transducers with a low constant contact pressure during RWW operation.
摘要翻译：用于高速和高密度多通道同时读写（RWW）操作的磁带头组件包括两个模块结合在一起。模块最初形成在一体的单元上并且成对地间隙，以产生良好的参考表面，这确保了完成的头部组件将满足严格的方位角和间隙公差。然后将该单元加工成两个分开的模块。进一步的处理涉及单独加工每个模块的头表面以实现期望的轮廓。加工的模块被测试并且以形成最终头部组件所需的位置布置组合在一起。在所公开的实施例中，总体轮廓使得组件能够在磁带穿过换能器之前将空气和碎屑从磁带的表面上滑落。轮廓允许带子在超支架上飞越，但是在RWW操作期间，传感器周围或周围的接触区域具有较低的恒定接触压力。

摘要： In a standard audio tape cassette, a new method of cleaning the capstan(s) while the tape is playing or recording. The new method and means consists of a fibrous material, generally a felt, which is positioned against the capstan(s) in a way so that when it is in contact it exerts a wiping pressure on the rotating capstan(s). Another means is by positioning the felt on a moveable lever which will bring the felt into contact with the capstan(s) when the cassette is in operating mode and not in contact when the cassette is not operating.

摘要： A head for a tape drive system has a plurality of transducers formed on a substrate and protected by a cover bar, with a tie bar bonded to the cover bar. The tie bar extends along a tape-facing surface beyond the cover bar, enhancing the structural integrity of the head. Wear bars may be bonded to the substrate, cover bar and tie bar. Alternatively, the tie bar may have a notch within which the substrate and cover bar are bonded. The tie bar reduces misalignment and instability of the transducers, providing increased storage capacity and greater reliability and durability of the tape drive system.

摘要： A cut out 23 is formed at the corner portion 22 which is formed between the second long side 822 and each of the first and second short sides 811 and 812 of the back yoke 5, in which the terminal stands 20d of the bobbins 20 of the read/write coil 6 and the erasing coil 7 are disposed respectively, a shield cover 32 is provided in such a manner as it is coupled with the first, second and third leg portions 10a, 10b and 10c including the wiring 6A of the read/write coil 6 and the wiring 7A of the erasing coil 7 and the front core 3 is bonded to the outer body 8 and the shield cover 32. Thereby, the bridging portion which has been necessary in the conventional example is almost eliminated, as a result, the strength of the front core 3 is increased to prevent it from being broken due to any shocking force. Since the terminal stands 20d of the read/write coil 6 and the erasing coil 7 are accommodated in the cut out 23 and not positioned outside the back yoke 5, to that extent, the apparatus is planned to be miniaturized.
摘要翻译：切口23形成在形成在第二长边822与后轭5的第一短边811和第二短边811中的每一个之间的角部22处，其中，线架20的端子架20d 读取/写入线圈6和擦除线圈7分别设置有屏蔽盖32，其与第一，第二和第三脚部10a，10b和10c耦合，包括读取/写入线圈6的布线6A，写入线圈6和擦除线圈7的布线7A和前芯3被接合到外部主体8和屏蔽罩32.由此，传统示例中所需的桥接部分几乎被消除，结果增加了前芯3的强度，以防止其由于任何冲击力而被破坏。由于读取/写入线圈6的端子架20d和擦除线圈7被容纳在切割部23中并且不位于后部轭铁5的外侧，所以该装置被计划为小型化。

The method includes the steps of: providing a tape drive with a head cleaning device, a data tape cartridge having data tape, and a cleaning tape cartridge having cleaning tape; detecting error rate for the transducer head with the data tape; determining when the detected error rate exceeds a specified level; and when the detected error rate exceeds a specified level, loading the cleaning tape cartridge into the tape drive and running cleaning media on the cleaning tape over the transducer head to clean the transducer head. Another method includes using a head cleaning device to clean the transducer head when there is an identified need, or as a preventative measure.

摘要： A device for cleaning the magnetic head of a disk drive mainly formed from a lower plate having a notch at a front end thereof, an upper plate closed to the lower plate and having an opening at a front end thereof corresponding to the notch of the lower plate, a cleaning element disposed in the opening of the upper plate, and a shutter closing the opening of the upper plate to hold the cleaning element in place. A reflex induction element is mounted in the device on the lower plate. When the device is inserted into a disk drive, the magnetic head of the disk drive is induced by the reflex induction element to move outward and contact with the cleaning element via the notch and the opening. Dust and impurities on the magnetic head are therefore removed by the cleaning element.

摘要： A tape drive read/write head assembly that utilizes a magnetic shield to help protect the head from any magnetic flux that strays from the tape drive's motor. The head assembly includes a voice coil motor, a transducer head (typically a read/write head), and a carriage carrying the head. The carriage is movably coupled to the motor. The magnetic shield is positioned at least partially between the head and the motor. In one preferred version of the invention, the shield is a metal plate sandwiched between the head and the carriage. It is desirable to make the shield from a high nickel content metal or similar type material that has a large magnetic flux carrying capacity with a small magnetizing force.
