摘要： Disclosed in an arrangement to achieve satisfactory head contact by increasing contact face pressure at a head gap and to reduce the change in time of head contact performance in a double azimuth head. Heads in a portion in which a tape is slid are respectively constructed with each head having two different arcs with a radius of curvature R1 in a first area which includes a gap, and with a radius of curvature R2 in a second area which is adjacent to the first area. A transition portion P for transitioning an arc with the radius of curvature R1 and an arc with the radius of curvature R2 is located in the direction of its adjacent head based upon a contact point Q on R1 of a common tangent drawn from an arc forming a periphery of a rotating drum to a circle formed by R1. The relationship between the radiuses of curvature in two areas is set to R1>R2. As the area in which a tape is in contact can be reduced, contact face pressure by the tape on a gap can be increased, satisfactory head contact can be obtained and as a contact area with a tape is wide to some extent, a change in time of contact performance can be reduced.

摘要： In a rotary head drum of a recording/reproduction apparatus, for smoothly holding a magnetic tape over a guide step provided on a lower drum to guide the magnetic tape, part of a chamfer formed in the guide step is formed as a large chamfer in which a chamfered amount is larger than that of the remaining part of the chamfer. With the provision of the large chamfer, even if the lower edge of the magnetic tape deviates from the guide step when the tape is wound over or unwound from the drum, damages of the magnetic tape can be prevented. Therefore, the position and attitude control of tape withdrawing members can be greatly simplified and the magnetic tape can always run stably while being restricted in its position by the guide step. In the process of machining a tape running surface on the drum, by increasing the feed distance of a blade in the part of the chamfer where the large chamfer is to be formed by chamfering the guide step with a large chamfered amount, in comparison with the feed distance set in the remaining part of the chamfer, the large chamfer and the small chamfer can be both machined at the same time, resulting in simplified machining steps.
摘要翻译：在记录/再现装置的旋转磁头鼓中，为了平滑地将磁带保持在设置在下磁鼓上的引导台上以引导磁带，形成在引导步骤中的倒角的一部分形成为大倒角，其中倒角量大于倒角剩余部分的倒角量。通过设置大倒角，即使当磁带从磁鼓卷绕或退绕时磁带的下边缘偏离引导步骤，也可以防止磁带的损坏。因此，能够极大地简化卷取装置的位置和姿势控制，并且通过引导步骤限制在其位置，磁带总是可以稳定地运行。在加工滚筒上的带子运行表面的过程中，通过在倒角部分中增加叶片的进给距离，通过以较大的倒角量倒角引导台阶，形成大倒角的部分，与在倒角的剩余部分设置的进给距离，大倒角和小倒角可以同时加工，从而简化了加工步骤。

摘要： A magnetic tape cartridge includes a casing having a tape chamber defined therein for accommodating a reeled magnetic recording tape and, also, box arms protruding outwardly from a front wall section of the casing so as to leave a loading bay that opens upwardly, frontwardly and downwardly and is thus delimited by upwardly, frontwardly and downwardly oriented open areas. The casing includes a lid assembly for selectively concealing and exposing that portion of magnetic recording tape and including front, top and rear lids operatively linked together. The front and top lids are adapted to selectively open and close the frontwardly and upwardly oriented open areas of the loading bay, respectively, while the rear lid is positioned within the loading bay and adapted to selectively open and close a space delimited between the front and the rear lid. At least first and second, generally cylindrical bosses extend between the top and bottom panels of the casing and are positioned at respective points of intersection between inner side walls of the box arms, which confront the loading bay, and the front wall section so as to partially protrude laterally into the loading bay. Each boss has a positioning hole defined axially therein so as to extend exteriorly through one of the top and bottom walls of the casing and is comprised of upper and lower boss segments aligned axially with each other. The upper boss segment has an outer diameter smaller than that of the lower boss segment.
