Abstract: A safety system for online servicing of a media library is provided, wherein the library comprises a plurality of media storage cells and at least one media picker robot that moves along the media storage cells, and wherein the library is contained within an enclosure having at least one access means. The safety system detects whether the access means in the enclosure is open or closed and operates the robot in the media library in one of two corresponding modes. If the access means is closed, the robot operates in a normal mode at a first specified speed. If the access means is open, the robot operates in a safe mode at a second specified speed that is slower then the first speed of the normal mode. In another embodiment, while in safe mode, the picker robot is excluded from moving within a restricted zone in the library.

Abstract: A multilayered ferromagnetic laminate includes a first magnetic film having a cobalt alloy and a second magnetic film having an iron-nitrogen alloy. The films are deposited upon one another and laminated to provide a multilayered film structure having an alternating plurality of the first and second magnetic films. The cobalt alloy may be a cobalt-zirconium-tantalum alloy. The nitrogen is incorporated interstitially in the crystalline structure of the iron of the second magnetic film. The laminate forms the magnetic shields and the write poles of magnetic disk and tape heads. The lamination of the first magnetic film which has high electrically resistive, high mechanical hardness, and high magnetic moment characteristics with the second magnetic film which has lower electrically resistive and very high magnetic moment characteristics yields the laminate which has very high magnetic moment and very hard pole material characteristics and has the ability to write at high frequencies.

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. An upper section is provided with a concave surface that curves upward to a circular edge around the top of the guide. The guide also includes a cylindrical central section, and a frustoconical lower section having its smaller-diameter end contiguous with the cylindrical section. Thus, the lower section provides a tapered outer surface extending downwardly from the central section. A tape is wrapped around the guide, whereby the tape is directed along its path of travel. As the tape moves along its path of travel, the curved upper section and tapered frustoconical section apply downwardly directed and upwardly directed biasing forces, respectively.

Abstract: A system of rollers and guides that adjust a wrap angle of tape around a guide in a tape cartridge. The system of rollers is an outer guide and an inner roller connected to a spindle via rigid arms. The tape extends around the reel and around a portion of the outer diameter of the outer guide. The inner roller rolls against the tape pack as the tape is wound or unwound around the reel. As the radius of the tape pack changes, position of the inner roller relative to the reel changes, causing the spindle to rotate. In turn, the rotation of the spindle causes a change in the position of the outer guide relative to the reel. As outer guide moves inwardly or outwardly relative to the reel, the wrap angle of the tape around the outer guide changes.
