摘要： A recording/playback apparatus including a stationary drum on which a traveling magnetic tape is wound, a plurality of magnetic heads for recording and playing back data, a rotary portion which is rotated while carrying the heads thereon, a drive portion which drives the rotary portion, an air injection device which spouts air from the vicinities of the magnetic heads toward the magnetic tape in order to separate the tape from the heads, and a control device which controls the start and stop of the air spouting of the air injection device. In the standby mode of the apparatus, in which the rotary portion is rotated though the heads perform neither the recording nor the playback operation, the tape is separated from the heads, so that the heads are prevented from wearing away. As soon as the standby mode has ended, the tape is brought into contact with the heads, so that the recording or playback operation can be immediately started.
摘要翻译：一种记录/播放装置，包括：卷绕有行进磁带的固定滚筒;多个用于记录和再现数据的磁头;旋转部，其在携带磁头的同时旋转;驱动部，其驱动旋转部一个喷射装置，其从磁头附近向磁带喷射空气，以便将磁带从头部分离;以及控制装置，其控制空气喷射装置的空气喷射的开始和停止。在设备的待机模式中，旋转部分通过头部既不进行记录也不执行重放操作而旋转，所以带与头部分离，从而防止头部磨损。一旦待机模式结束，磁带与磁头接触，从而可以立即开始记录或重放操作。

摘要： A magazine in which a plurality of cartridges are contained as vertically moved stepwise by a distance separating two successive ones of the cartridges. The lift has a plurality of lift steps alternately engaged by a latching member. A rotary disk having two pins on its face is arranged adjacent the latching member. During rotation of the disk, one of the pins pivots the latching member out of engagement with a lift steps while the other of the pins supports the disengaged lift step to raise or lower the lift, depending upon the rotational direction of the disk. Further rotation of the disk permits the spring biased latching member to pivot back into a path where it engages the next lift step, thereby accomplishing one step of movement of the lift. Each time the lift is moved by one step, a pinch roller arrangement detects whether a cartridge is in the magazine corresponding to the position currently aligned with the inlet/outlet of the tape changer. If a cartridge is present, then the pinch rollers move the cartridge to load it into a magnetic tape unit, otherwise the lift is moved by another step, and the presence of a cartridge at the new position is detected. In this way, all of the cartridges present in magazine are sequentially loaded into the magnetic tape unit and after being ejected from the magnetic tape unit are loaded back into the magazine.
摘要翻译：其中容纳多个墨盒的盒子以分离两个连续的墨盒的方式逐步地垂直移动。升降机具有由闩锁构件交替地接合的多个提升台阶。在其表面上具有两个销的旋转盘设置在闩锁构件附近。在盘的旋转期间，其中一个销使闩锁构件与升降台摆动而脱离接合，而另一个销支撑分离的升降台阶，以根据盘的旋转方向升高或降低升力。盘的进一步旋转允许弹簧偏置的闩锁构件枢转回到其中接合下一个升降台阶的路径，从而实现升降机的一个移动步骤。每次升降机移动一步时，夹紧辊布置检测墨盒是否在与当前与带式更换器的入口/出口对齐的位置上的盒子中。如果存在盒式磁带，则夹送辊移动盒式磁带将其装入磁带单元，否则升降机移动另一步，并且检测到位于新位置的盒的存在。以这种方式，存储在盒中的所有盒被顺序地加载到磁带单元中，并且在从磁带单元被弹出之后被装回到盒中。

摘要： A magnetic recording and reproducing device and a magnetic tape library device are provided for properly recovering a function and issuing a warning when a failure of a magnetic head of the device takes place because of wear and dirt of the magnetic head. Further, a method for maintaining the magnetic head is provided. A wear sensor and a dirt sensor are prepared for sensing a wear amount of a state of dirt of the magnetic head. A head check controller operates to determine the wear amount of the magnetic head and the state of dirt based on the sensed result. In accordance with the determined result, the warning device is started for taking a precaution of preventing a head failure. As one aspect, the tape library device instructs to load the cleaning tape using a robot.

摘要： A load torque imposed on a take-up reel motor is estimated from the current in a take-up reel motor and the rotational speed of the take-up reel. The current value supplied to the take-up reel motor is adjusted on the basis of the estimated load torque. A tape feed rate detected is compared with a reference signal produced from a target tape speed signal. On the basis of the comparison result, the torque of the take-up reel motor is controlled in such a manner that the tape feed rate assumes a predetermined value. The gain of a speed control system for controlling the rotational speed of the take-up reel is adjusted on the basis of a detected period of tape speed.

摘要： As a method of increasing the storage capacity of a magnetic recording and reproducing apparatus for recording and reproducing information to and from a magnetic tape in a cartridge, there is a helical scan recording method in which the magnetic tape is diagonally wound around a drum which rotates a magnetic head. With an apparatus adapted to this method, the disposition of the cartridge and the take-up reel for taking up the magnetic tape on the same plane arises a necessity of considerably bending the magnetic tape at the drum portion and, accordingly, the magnetic tape is damaged. In order to prevent the damage of the foregoing type, the tape passage surface from the cartridge to the drum and the tape passage from the drum to the take-up reel are formed by an angle at which the direction in which the magnetic tape is moved is changed due to winding of the magnetic tape around the drum so that the magnetic tape is not bent excessively. A threading device capable of three-dimensionally controlling the position of the magnetic tape in accordance with a predetermined tape passage is provided for the apparatus structured as described above. The threading device is formed by a link mechanism to be moved along the locus of a cam groove so that the three-dimensional position control can be performed.

摘要： In a tape loading device of the invention, a tape is taken out by tape guides mounted on an inclined loading ring, and the loading ring is rotated to wind the tape on a rotary drum from one side thereof. An auxiliary inclined guide is provided between the rotary drum and the leading tape guide. Only during a loading operation, the auxiliary inclined guide contacts the tape, while angularly moved about the leading tape guide. When the loading operation is completed, the auxiliary inclined guide is disengaged from the tape. With the provision of the auxiliary inclined guide, the tape is prevented from being twisted between the rotary drum and the leading tape guide.
