Abstract: The removable optical disc storage cartridge stores a plurality of optical disc media in a substantially stacked orientation for later extraction and presentation to a picker in an optical disc storage library. Each optical disc media is stored on a separate extractor that slides between a retracted and a stored position. An extractor tab, accessible outside or inside of the removable optical disc storage cartridge, is connected to each one of the extractors located within the removable optical disc storage cartridge. The removable optical disc storage cartridge further includes a security front door that operates between a closed and open position and further includes a locking element. The locking element may be operated by the picker or a release element contained on a magazine that handles multiple disc storage cartridges. The removable optical disc storage cartridge also includes seals to prevent dust from entering the removable optical disc storage cartridge.

At least a portion of the body extends through an area of fluid flow such that a plane containing the wavy path lies substantially parallel to the direction of flow. In one embodiment, the longitudinal axis extends along a substantially sinusoidal path. Also disclosed is a method of reducing drag on and suppressing vortex induced vibrations in an elongate body disposed in an area of directional fluid flow, comprising the steps of coupling at least one end of the body to a support, forming a longitudinal axis of the body along a wavy path, and orienting the body such that the wavy longitudinal path lies in a plane substantially parallel to the direction of fluid flow.

Abstract: A helical scan transport apparatus for reading and writing data on to a magnetic recording tape which is wound on a supply reel rotatably mounted within a removable tape cartridge includes a chassis having a front end portion and rear end portion. An elevator assembly is mounted on the chassis at the front end. The elevator assembly is configured to receive the tape cartridge and to position the tape cartridge in a loaded position. A take-up reel assembly is coupled to the chassis at the rear end position. A helical deck is mounted on a central portion of the chassis between the elevator assembly and the take-up reel assembly. The helical deck includes a rotary read/write head, a substantially linear tape loading path between the elevator assembly and the take-up reel assembly, and a movable guide for the seizing the tape from the tape loading path and for at least partially wrapping the tape around the rotary head.

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.

Abstract: The improved magnetic tape cartridge includes a leader block retainer mechanism that provides a positive locking function to automatically secure the leader block in place in the opening of the magnetic tape cartridge housing. The leader block retainer mechanism comprises detent members springably attached to both the top and bottom sides of the housing, juxtaposed to the opening, to engage corresponding features on the leader block to resist withdrawal of the leader block from the housing.

Abstract: A system is disclosed which threads a tape media leader block from a 3480-type cartridge to a takeup reel by aligning the tape media directly above the tape threading path, seating the leader block in the takeup reel, and lowering the tape media downwards onto the helical tape threading path guides by concurrently lowering the takeup reel and the tape cartridge onto the associated drive motor spindles. When the tape media is thus positioned in the tape threading path, the helical scan mechanism can then operate in conventional fashion to wrap a length of the tape media around the scanner for reading and writing data on the tape media.

Abstract: A mechanism for defining a write protect state of a data storage media enclosed in a housing of a data storage element is disclosed. The mechanism includes an aperture formed in an exterior surface of the housing, wherein the aperture has a first region and a second region. A member is movably secured within the aperture and is manually moveable between a first position wherein the member is positioned proximate the aperture first region, and a second position wherein the member is positioned proximate the aperture second region. A first human intelligible mark is placed on the housing proximate the aperture first region. The first human intelligible mark depicts a portion of a predetermined symbol corresponding to one of a write enabled state and a write protect state of the data storage media. A second human intelligible mark is placed on the member. The second human intelligible mark depicts a remaining portion of the symbol.

Abstract: This magnetic tape cartridge has the same exterior dimensions as a conventional 3480-type magnetic tape cartridge but houses different media. To clearly identify the media contained in the cartridge, a label receiving recess in included on the back of the cartridge. A human readable and machine readable label can be inserted into this recess to identify the media contained in this cartridge. Additional label recesses are provided juxtaposed to the media identification recess and on the top and side of the cartridge to receive user installed labels to uniquely identify the cartridge.

Abstract: A linear threading apparatus for threading a tape through a predetermined path in a tape transport mechanism. The tape transport mechanism typically has an elevator assembly to receive a single-reel tape cartridge having a web of tape and a leader block, a tape drive assembly for reading and writing data on the tape, and a take-up reel assembly for receiving the tape. The linear threading mechanism includes a platform having a cam track positioned above the predetermined path that the tape is to travel. The platform has a linear bearing mechanism which provides a linear track from a point proximate to the elevator assembly to a point proximate to the take-up reel. A linear arm is attached to and travels freely over the linear bearing mechanism. Pivotally attached to the linear arm is a threading arm which is coupled with and travels in the cam track as the linear arm travels along the linear bearing mechanism. The linear arm is connected to and controlled by a belt and motor assembly.

Abstract: A universal data storage element presents a data storage element of uniform form factor while enables the selection of media types to provide variable data recording characteristics. Using multiple types of media in an automated library system or a manually operated media storage retrieval system is now possible with a uniform form factor exists in all of the data storage elements. Physical characteristics of the media are identified by a plurality of coding apertures outside the data storage element. A drive element decodes and identifies the type of media from the apertures.
