摘要： A mechanism prevents uneven take-up of a tape on a take-up reel. This mechanism includes a roller guide having a first flange for guiding a first edge of the tape so as to position the tape in a direction perpendicular to a transport direction of the tape, and an arm roller which pushes against a part in a vicinity of a second edge of the tape which is taken up on the take-up reel, where the second edge is opposite to the first edge.

摘要： Disclosed herein is a magnetic tape unit having a magnetic head for reading and writing data from and onto a magnetic tape. The magnetic tape is traveled in contact with the magnetic head during a read/write operation of the magnetic head. During a rest period where the read/write operation of the magnetic head is not performed, a reciprocating motion of the magnetic tape by a small distance is performed with a predetermined period. A temperature in the vicinity of the magnetic head is detected by a temperature sensor. The predetermined period is changed according to the temperature detected by the temperature sensor. Accordingly, the adhesion of the magnetic tape to the magnetic head can be well prevented irrespective of the temperature inside the tape unit.

摘要翻译：这里公开了一种磁带单元，其具有用于从磁带读取和写入数据的磁头。在磁头读/写操作期间磁带与磁头接触。在不执行磁头的读/写操作的休息期间，以预定的周期执行磁带的一定距离的往复运动。通过温度传感器检测磁头附近的温度。预定时间根据由温度传感器检测到的温度而改变。因此，与磁带单元内的温度无关地，可以很好地防止磁带对磁头的粘附。

摘要： A tape threading mechanism for a magnetic tape unit uses a cartridge-contained magnetic tape with a leader-block attached at an end of the magnetic tape. The tape threading mechanism pulls out the leader-block from the cartridge, performs a tape threading/unthreading and inserts the leader-block back into the cartridge by way of a threading arm. The threading arm is connected to a rotational axis thereof at a first end. A second end of the threading arm is provided with a pin for carrying the leader-block and includes a linkage of at least two arms. At least one of the two arms has an elastic member which allows the threading arm to expand and contract lengthwise.

摘要： A magnetic tape unit with a magnetic head for reading and writing data from and onto a magnetic tape. The magnetic tape is kept in constant contact with the magnetic head, and a reel motor travels the magnetic tape kept in contact with the magnetic head. Adhesion of the magnetic tape to the magnetic head is prevented by slowly driving the reel motor to travel the magnetic tape at a speed lower than a normal traveling speed for a read/write operation of the magnetic head, during a rest period when the read/write operation of the magnetic head is not performed.
