  • Patent number: 7474513
    Abstract: A magneto-resistive (MR) transducer is capable of reading data signals magnetically recorded on a tape. The transducer includes a head-tape interface (HTI) and a MR sensor adjacent to the HTI. An electro-static discharge (ESD) element is coupled to the MR sensor, which is adapted to provide an electrical path from the MR sensor to a lower potential structure.

  • Patent number: 6663034
    Abstract: A data storage tape cartridge is disclosed including a housing, a single tape reel, a storage tape, and a leader block. The housing includes a front, a back, a first side, a second side, a top, and a bottom. Further, the housing forms a leader block window, a lateral datum pad, and a longitudinal datum pad. The leader block window is formed at a corner defined by the front and the first side. The lateral datum pad is formed in the top. Finally, the longitudinal datum pad is formed in the front. The single tape reel is rotatably maintained within the housing. The storage tape is wrapped about the tape reel. The leader block is coupled to a leading end of the storage tape and is selectively secured to the housing at the leader block window. With this configuration, the lateral datum pad is configured to identify a top-to-bottom position of the tape reel. Similarly, the longitudinal datum pad is configured to identify a front-to-back position of the tape reel.

  • Patent number: 6477010
    Abstract: A data storage tape cartridge including a housing, at least one tape reel, and a storage tape. The housing defines a top face, a bottom face, a front, a back, and opposing sides. Further, the housing forms a tape identification notch, a write-select notch, a first misinsertion notch, and a second misinsertion notch. The tape identification notch extends from the front of the housing along one of the opposing sides. The write-select notch is formed in the front of the housing and is configured to maintain an insert piece. The first misinsertion notch is formed in the front of the housing and is configured for clearance about a tape drive switch. Similarly, the second misinsertion notch is formed in the front of the housing and is configured for clearance about a tape drive switch. The first and second misinsertion notches are substantially aligned. The at least one tape reel is rotatably disposed within the housing. Finally, the storage tape is maintained by the at least one tape reel.

  • Patent number: 6452747
    Abstract: A data storage tape cartridge for use with a high speed tape drive as part of a tape drive system. The data storage tape cartridge includes a housing, at least one tape reel, a storage tape, a brake body, and a spring. The housing defines an enclosure and forms an opening for accessing the enclosure. The tape reel is rotatably disposed within the enclosure, and defines a central bore. The tape reel maintains the storage tape. The brake body is disposed within the central bore of the tape reel and includes a stem, a reel engagement section, and a button. The stem is slidably connected to the housing. The reel engagement section is configured to selectively engage a portion of the tape reel in a locked position. The button is positioned opposite the stem and terminates in a leading end. In a preferred embodiment, the leading end forms a concave surface configured to selectively receive a rounded surface associated with a tape drive. Finally, the spring biases the brake body to the locked position.

  • Patent number: 6154342
    Abstract: A data storage tape cartridge having a reinforcing tape reel lock. The data storage tape cartridge includes a housing defined by a first housing section and a second housing section, a hub pin extending from an interior surface of the first housing section, a tape reel assembly rotatably maintained by the hub pin and a storage tape wrapped about the tape reel assembly. The tape reel assembly includes a hub, opposing tape flanges and a brake body. The hub includes a tape receiving portion interiorly secured to a post, the post defining an axial bore sized to receive the hub pin. The brake body is retractably associated with an axial end of the hub and includes a braking surface and an interior support surface. The braking surface is configured for selective engagement with the second housing section. The interior support surface is configured to abut the post of the hub.

  • Patent number: 6069777
    Abstract: A data storage tape cartridge having an exposed base plate datum for improved tape registration. The data storage tape cartridge includes a housing defined by a first housing section and a second housing section, a base plate, at least one tape reel and a storage tape. The base plate is disposed within the housing and includes a reference portion that is exposed through a protected opening in the first housing section. In one preferred embodiment, the first housing section protects the base plate, including the reference portion. The at least one tape reel is rotatably associated with the base plate. Finally, the storage tape is maintained by the at least one tape reel within the housing. Upon insertion of the data storage tape cartridge into a tape drive, a registration device engages the reference portion of the base plate to determine and precisely control location of the storage tape relative to a read/write head.

  • Patent number: 5969913
    Abstract: A data storage tape cartridge having a misinsertion notch. The data storage tape cartridge includes a housing, a tape reel and a storage tape. The housing includes a base and a cover, each defining a front, a back, a first side and a second side. The misinsertion notch is defined in the base, extending from the front of the base and along the first side of the base. The misinsertion notch has a length less than approximately one-half a length of the first side of the base for facilitating proper insertion into a receiving frame.

  • Patent number: 5629815
    Abstract: An apparatus for reducing head wear in a helical scan tape transport passes a flow of relatively clean, dry air through a transport housing without allowing the flow of air to flow directly across the rotary head assembly. Air from a fan positioned at a rear portion of the transport cools a power supply and creates a positive air pressure within the transport housing. The air is heated by the power supply before it passes through the transport housing, so that only relatively "dry" air reaches the rotary head assembly. The air is exhausted out the opening through which a tape is loaded. This arrangement substantially reduces the possibility of contaminants entering the transport housing. Additionally, the air cleans a magnetic recording tape on a tape cartridge as the tape is passes through the transport housing so that only relatively "clean" tape reaches the rotary head assembly.
