  • Patent number: 7800863
    Abstract: A tape guide is provided for use in routing a tape media, used in a computer or other application, along a pre-specified path of travel. The tape guide is oriented along a vertical axis and comprises three sections or components joined together to form an integral guide structure. Upper and lower sections both comprise frustoconical sections, the respective dimensions of the two frustoconical sections being equal to one another in a useful embodiment. A tape is wrapped around the guide, whereby the tape is directed along its path of travel. As the tape moves, the upper and lower sections apply downwardly and upwardly directed biasing forces, respectively, to maintain the moving tape in an equilibrium position in order to avoid contact between the edges of the tape and any guide structure.

    Abstract: A tape guide in a tape cartridge for use with a tape drive includes a fixed shaft and a cylindrical sleeve positioned around the shaft. The sleeve has an inner surface and an outer surface. The inner surface of the sleeve engages the shaft such that there is friction between the sleeve and the shaft. This friction is overcome by friction between tape and the outer surface of the sleeve when the tape engages the outer surface of the sleeve causing the sleeve to rotate around the shaft as the tape moves. The friction between the tape and the outer surface of the shaft decreases below the friction between the sleeve and the shaft once the tape moves at a velocity sufficient to develop an air film between the tape and the outer surface of the sleeve causing the sleeve to cease rotation around the shaft.

  • Patent number: 5865389
    Abstract: An air dam (35) is place between free tape (13) extending to a reel (11) and the reel (11). During high speed winding operations, the air dam (35) interrupts air flow toward the convergence (17) of the free tape (13) with the reel (11). This reduces a tendency for air entrainment in tape (15) packed on the reel (11) during the high speed winding operations.

  • Patent number: 5772143
    Abstract: A guidance system for tape in a tape cartridge includes two corner guides and an optional third guide. The two corner guides may be angled to produce a bow in the tape. If provided, the third guide is readily adjustable during manufacture to an exact predetermined distance from the two corner guides, thereby avoiding problems due to build-up of manufacturing tolerances. A method of constructing such a system provides an interference fit ferrule on a pin as the third guide, such that the position of the ferrule can be adjust to the exact position desired during manufacture.

  • Patent number: 5769356
    Abstract: A tape guide structure, for use in a video cassette recorder ("VCR") into which a tape cassette is loaded, comprises a guide post and a post cap. The guide post is provided with a lower cylindrical portion and an upper cylindrical portion with a diameter less than that of the lower portion. The guide post is fixed to a deck. The post cap is provided with a head portion with a slant surface and is fixed on top of the guide post. According to the tape guide structure of the present invention, even though the tape cassette is loaded into the VCR with the tape loosened to the extend that it passes over the central axis of the guide post, the tape comes in contact with the slant surface of the head portion, thereby allowing the tape to be loaded into a correct position.

  • Patent number: 5758836
    Abstract: A data tape cartridge is formed on a baseplate of polymeric material which supports mounting pins and tape guides thereon for supporting tape components in rigid and dimensionally-stable manner using integrally formed bosses to support the mounting pins and guides. Additional stability against flexure is achieved using a matrix pattern of integrally-formed webs or ribs and sidewalls in the baseplate and by attaching a top plate substantially about the entire perimeter of the sidewalls. Lateral forces exerted against rotatable components on the mounting pins are transferred to the baseplate and top plate by the mounting pins that are supported in both plates. A midguide support is integrally formed in the baseplate to support a guide pin at critical location adjacent the location along the tape path in the cartridge at which a tape transducer interacts with tape.

  • Patent number: 5754378
    Abstract: A tape cassette in which fixed guide pins (9), (10) are disposed at positions in which a wrapping angle at which a magnetic tape is wound around the fixed guide pins (9), (10) when the magnetic tape is transported is reduced that is the position at which the tape wrapping angle does not exceed 40.degree. wherein, a frictional force generated between the fixed guide pins (9), (10) and the magnetic tape (3) when the magnetic tape (3) is transported is reduced as compared with a conventional tape cassette, whereby a load on a motor for transporting the magnetic tape (3) is reduced, resulting in a life of a battery being extended.

  • Patent number: 5716018
    Abstract: A tape guide for a digital tape mini-cartridge providing decreased tape wander in a direction transverse to the intended path. The guide provides an increased area of tape having increased transverse stiffness without interfering with an adjacent drive wheel. In one embodiment, the guide is cylindrical and has a cylindrical cut-out to provide clearance for an adjacent cylindrical drive wheel. Preferably, the guide has top and bottom flanges. If a top flange of the guide is present, the cut-out continues through the top flange of the guide. The top flange of the guide may be relatively thin to fit below a top flange of the adjacent drive wheel. Alternatively, the top flange of the guide may have a larger cut-out to avoid interference with the top flange.

  • Patent number: 5689392
    Abstract: A tape cassette having a tape guide for contacting with a magnetic tape provided as a tape coil within a main cassette body, and guiding the running of the magnetic tape, is disclosed. The tape guide for guiding the magnetic tape is molded with a lower cassette half integrally from an ultra high molecular resin having a molecular weight ranging from 500,000 to 1,000,000 for simplifying the assembling process and reducing production costs as well as preventing adverse effects of deviation from true verticality of the tape guide on the magnetic tape during recording/reproduction or fast feed/rewind to assure stable tape running.

    Abstract: A tape cassette includes tape reels and a cassette main body formed of an upper shell and a lower shell. In such a tape cassette, a tape reel position restricting portion serving as a reinforcing member for the lower shell is provided on the lower shell at a position outside an outer periphery of the lower flange. The tape reel position restricting portion includes a high rib; an intermediate rib being lower than the high rib within a range not to obstruct passing of a tape end detecting light beam, and being positioned in a tape end detecting light path; and a low rib being lower than the intermediate rib, and being positioned in a tape path region. The intermediate rib and the low rib are preferably disposed outside the high rib.

  • Patent number: 5618005
    Abstract: The coaxial reel tape cartridge uses a lengthy tape path within the tape cartridge to reduce the stresses on the tape medium as it is transported between the two reels. The tape is drawn from each reel around a corresponding rotating guide element which is coplanar with the tape reel. The tape is then transported along one side of the tape cartridge exterior housing to a corresponding hydrostatic bearing which is located at a corner of the tape cartridge adjacent the tape access opening. The hydrostatic bearing is coplanar with the tape guide, but at a slight angle with the vertical to thereby impart a slight twist to the tape as it traverses the length of the tape cartridge. The two hydrostatic bearings are located inside of and at opposite ends of the tape cartridge exterior housing, flanking the tape access opening. The two hydrostatic bearings are attached to a base plate which maintains the hydrostatic bearings coplanar with respect to each other.
