摘要： A pressure flap for eliminating slack in a tape cassette. The pressure flap includes a body portion having a tape contact edge at a first end thereof, and a fold line at a second end thereof. The body portion is bowed along a line extending generally parallel to the fold line. The pressure flap also includes a folded portion extending contiguously from the fold line of the body portion at a predetermined angle. The body portion includes a pair of opposed lateral edges secured to a pair of opposed sides of the folded portion. In a preferred embodiment, the pressure flap is fabricated from carbon-filled, high-density polyethylene, and the opposed sides of the folded portion are fused to the lateral edges of the body portion during fabrication of the pressure flap.

摘要： A method and apparatus are provided for preventing contamination of a rotating magnetic disc by particles outgassed from or through the bearings upon which the disc is mounted for rotation. This is accomplished by maintaining a differential pressure aross the bearing nearest the magnetic disc compartment with the higher pressure inside the compartment so that any particles outgassed from the bearing or bearing chamber are constrained to migrate toward a region of lower pressure within the bearing chamber and therefore away from the magnetic disc compartment.

摘要： An open loop, stepper-motor-driven, rigid magnetic disc memory apparatus for use with a data processing system. A rigid magnetic disc with high track density is driven by a stepper motor in an open-loop fashion or without servomechanism control. The memory apparatus includes: band structure including a spring bias for coupling stepper motor drive to apparatus supporting magnetic heads above and/or below the spinning disc and for temperature compensating for disc/apparatus expansion and contraction; manually operable control for zeroing the magnetic heads, moving and locking them in the disc's landing zone as, for example, while in transit, and providing a travel limit to head movement when the memory apparatus is operating; keying apparatus for preventing erroneous insertion and mis-alignment of and damage to an optical transducer relative to an optical mask arranged to spin with the disc structure; shim apparatus for precisely positioning the magnetic heads in the spin axis direction; viscously-coupled inertia apparatus for damping the stepping motor's step-rotary motion; a device for employing spinning motion associated with the disc for cooling purposes; and other structure.

摘要： A memory disk drive unit uses a base casting in which the fan shroud and the filter housing chamber are integrally formed in the casting along with locating openings and surfaces for the motor mount, the disk, and the head positioning mechanism. A cover is placed over the disk and the head positioning mechanism and it has an opening in its upper surface. A circuit board having the majority of the electronic circuit components on it is mounted in the cover opening, thereby forming a closure for the top of the cover. Air under positive pressure passes from the filter housing chamber over the disk, past the head positioning mechanism and outward through an outlet opening in the cover adjacent to the disk drive motor. Most of the heat producing elements are located on the outside edge of the base casting and outside the enclosure for the disk. This minimizes temperature caused movements of the head, and the multi-purpose base casting and the electronics circuit board mounting substantially simplify the construction, assembly, and maintenance of the disk drive unit.

摘要： An arrangement for magnetic disk memories having a plurality of modular memory disk units in separate housings mounted in a single cabinet is described. Support yokes for each unit support a pair of hubs with the rotatable disk mounted between bearings in the two hubs. In addition, a closed, substantially circular, housing around the disk is mounted on the hubs to maintain dimensional stability relative to the disk in radial and circumferential directions. Magnetic recording heads are mounted on sides of the housing generally toward the periphery and are, therefore, maintained in precise position relative to the disk. Matched pairs of preloaded angular contact bearings are employed for mounting the disk on a shaft in the hub and both inner and outer races of the bearings are clamped in place. Undue loads on the bearings are prevented by making the housing with flexural rigidity in a direction along the axis of the bearings high enough to hold the recording heads in substantially fixed position and low enough to apply an insubstantial axial load on the bearings.
摘要翻译：描述了一种在安装在单个机柜中的分离的壳体中具有多个模块化存储盘单元的磁盘存储器的布置。每个单元的支撑架支撑一对轮毂，其中可旋转盘安装在两个轮毂中的轴承之间。此外，围绕盘的封闭的大致圆形的壳体安装在轮毂上，以在径向和圆周方向上保持相对于盘的尺寸稳定性。磁记录头通常朝向周边安装在外壳的侧面上，因此相对于盘保持在精确的位置。使用匹配的预加载角接触轴承对将盘安装在轮毂中的轴上，并且轴承的内圈和外圈均被夹紧就位。通过使壳体沿着轴承的轴线的方向具有足够高的弯曲刚度，将记录头保持在基本上固定的位置并足够低以在轴承上施加非实质的轴向载荷来防止轴承上的不适当的负载。

摘要： A temperature compensation system for a magnetic disk memory unit which is removable from a disk drive unit in which the transducer which is part of the track positioning system is located in the same temperature and mechanical environment as the magnetic disks and read/write heads. All active elements are kept at a substantially uniform temperature by proper air flow and temperature changes are compensated for by the use of similar materials in similar locations.

摘要： An air circulation control system for a magnetic recording disc drive employing a baffle pivotally mounted near the shroud which encircles the disc pack. A torsion spring holds the baffle in a retracted position against the shroud adjacent to the head access opening in the shroud for insertion and removal of disc packs. Rotation of the disc packs causes air flow across the baffle until the air flow pulls the baffle into the spaces between the discs of the disc pack. Thereafter the baffle causes an air pressure differential around the periphery of the disc pack which is used to pump cooling air through the disc drive.

摘要： A rotating magnetic disk is enclosed in a housing having at least one pair of ports. An external conduit having a filter therein interconnects the ports. The rotation of the disk imparts a velocity to the air adjacent to the disk faces and the interior of the housing provides an airflow guide which causes air from both sides of the disk to flow into a scoop disposed in one port and coupled to the conduit. Thus a high rate of air circulation through the conduit is achieved and the air is rapidly filtered.
