摘要： An apparatus, computer readable medium device, and method for controlling transportation of a tape medium. A determination is made whether to execute a backhitch operation in response to writing a data set to tape from the buffer. If not, a determination is made whether a transaction size at which data is transferred from the buffer to the tape is less than a buffer size. If so, then a determination is made of a a new speed and whether a current speed is different from the determined new speed. If so, then a backhitch is initiated.

摘要： A reel cover of a magnetic recording/reproducing apparatus having an improved assembly construction with respect to a chassis and a method of manufacturing thereof provide a reel cover assembled with the chassis in a manner where a plurality of protrusions of a reel cover body are inserted in a plurality of recesses formed on the chassis. In this state, a resilient member formed at the reel cover body resiliently contacts a side surface of the chassis so that the protrusions are kept within the recesses. The reel cover can be assembled with the chassis in a simple manner without requiring extra securing means such as screws. Accordingly, the number of assembly parts can be decreased and the assembly procedure may be simplified, thereby productivity may be improved and manufacturing cost may be reduced.

摘要： An idler mechanism for a magnetic tape device. An idler gear is swingingly displaced between first and second positions to selectively transmit rotation to one of a pair of reels. One end of an arm-like swinging member is coupled in a relatively rotatable manner to a center shaft of an input gear which always meshes with the idler gear and which is rotated forwardly and reversely. A shaft which is disposed on the other end of the swinging member is inserted in a relatively rotatable manner into a bearing hole of the idler gear. A surface of a flange which is disposed on the input gear is formed as a friction force applying face which extends radially outwardly so as to be inclined downwardly. An outer peripheral portion of the idler gear slidably comes into contact with the friction force applying face.

摘要： A magnetic recording/reproduction apparatus of the present invention, which records/reproduces information on/from a magnetic tape by passing the tape around a rotary head cylinder having a rotary head for a predetermined arc, includes: a capstan shaft; a pinch roller; a first reel base rotatably attached to a shaft; a second reel base rotatably attached to a shaft; and an idler supported swingably to swing to the second reel base when the capstan is rotated in a first direction and to the first reel base when the capstan shaft is rotated in a second direction, wherein the idler includes a gear portion which rotates in association with the rotation of the capstan shaft. The above components of the magnetic recording/reproduction apparatus are situated in such a manner that when the running of a magnetic tape is to be shifted from a first direction to a second direction, the rotation of the capstan shaft, in the first direction stops, the pinch roller moves away from the capstan shaft, the capstan shaft is rotated in the second direction by a predetermined amount so that the idler swings to the first reel base, the capstan shaft stops again, the pinch roller presses the magnetic tape against the capstan shaft, and the capstan shaft is rotated again in the second direction and the gear portion to be coupled with the first reel base, the gear portion rotating the first reel base in a direction in which the magnetic tape is wound onto the first reel.

摘要： A tape guide system includes a rotary head drum inclined by a predetermined angle relative to a mechanical chassis of a recording and/or reproducing apparatus on which the head drum is mounted. A guide roller extends essentially vertically relative to the mechanical chassis on a side of the rotary head drum. An inclined guide post is arranged between the rotary head drum and the guide roller along a tape path. The inclined guide post is inclined at a first angle relative to the mechanical chassis. The first angle is a theoretical angle plus an additional offset angle. The offset angle lies in a direction parallel to a tape surface in contact with the side of the rotary head drum. The theoretical angle is derived from predetermined parameters including an inclination angle of the rotary head drum relative to the mechanical chassis and a tape-wrap angle at which tape is wound onto the rotary head drum.
