    Abstract: A method and system are disclosed for improved edge detection on tapes. By use of a nominal tape having a 100% output, a write head writes with a given write current onto the nominal tape and the output level is read with a read head during a calibration procedure in order to determine a reference level for the 100% nominal tape. Thereafter, when an actual tape is being used, by use of the same write current, a signal is written on the actual tape and is subsequently read to create a read output. That read output is compared to the reference level output derived during the calibration to create a correction factor. The correction factor is then employed to correct a trigger point utilized during a subsequent tape edge determination.

    Abstract: In a tape cartridge of the type used to store data on a magnetic tape in a high-speed data storage and retrieval system, the tape must be maintained at a proper tension within the cartridge so as to maintain the tape taut against the write/read head. Slackness in the tape occurs after a repeated number of changes in the tape transport direction or start/stop events, because the tension experienced by the tape is not the same in both transport directions. A method and apparatus for maintaining tape tension are disclosed wherein a selected tape characteristic is monitored, the characteristic changing as the tape tension changes. If the monitored characteristic exceeds a predetermined value, or after the passage of a selected amount of time, when the next reversal of tape transport direction occurs, the tape is moved a selected distance longer than necessary to effect the reversal so that when a desired data location on the tape reaches the location of the write/read head, the tape will again be at the proper tension.

    Abstract: A housing of a tape drive is adapted for sideways loading of a cartridge. The cartridge is loaded such that three reference points defining a fixed plane within the housing engages the cartridge in a fixed orientation with respect to a head within the drive. The cartridge is canted after the cartridge is engaged at a first one of the three reference points so as to fixedly engage the cartridge at each of the three reference points.

    Abstract: A magnetic head which contacts the magnetic tape (11) comprises a ferromagnetic body (12). A recess (26) is provided in this ferromagnetic body (12). A ferromagnetic core (9) has pole tips (9a,9b) which are located in the recess and which are arranged for contact with the magnetic tape. A non-magnetic material (18,20,21,22) is arranged along each side of the magnetic core pole tips in the recess. Relative hardnesses of the ferromagnetic body, ferromagnetic core pole tips, and non-magnetic material are chosen so that as the tape (11) wears away on contact surfaces of the magnetic core pole tips, non-magnetic material, and ferromagnetic body, the core pole tips (9a,9b) protrude relative to adjacent portions of the ferromagnetic body and the non-magnetic material so that the tape rides on the protruding pole tips of the core. A radius of curvature at the contact surface of the magnetic core pole tips prior to wearing of the pole tips is chosen such that it is smaller than a natural radius of bending of the tape.
