摘要： Disclosed are a system, a method, and an article of manufacture to provide for the detection and compensation of tape breakage in a tape drive. The invention operates by simultaneously monitoring the tape reel rotation direction and the ratio of rotation between the tape reels. If the rotation direction is not the same for both reels, then tape breakage is indicated and reel rotation ceases. Tape breakage is also detected if the tape reel angular rotation ratio between the supply and take up reels is not within a specified tape reel ratio range. The tape reel angular rotation ratio is detected by simultaneously measuring the angular rotation of each tape reel in a specified time period and then calculating the ratio. The present invention detects the tape reel angular rotation ratio and if tape reel angular rotation ratio is outside of the specified tape reel ratio range, tape breakage is indicated and reel rotation ceases.

摘要： A method to monitor the relative position of a magnetic tape disposed in a tape drive, where that tape drive includes a first tape reel motor and a second tape reel motor. The method provides a magnetic tape disposed on a first tape reel, and releaseably attaches the first tape reel to the first tape reel motor. The method further provides a second tape reel attached to the second tape reel motor. The method operates the first tape reel motor and the second tape reel motor to transfer the tape from the first tape reel onto the second tape reel while maintaining a running second reel rotation count. The method sets a second reel rotation count limit, and determines if the running second reel rotation count exceeds that second reel rotation count limit. If the running second reel rotation count exceeds the second reel rotation count limit, then the method discontinues operation of the tape reel motors.

摘要： In a tape having separate servo bands of patterns positioned laterally across the tape, the patterns of a separate servo band have at least one differentiating characteristic with respect to patterns of another of the separate servo bands. The differentiating characteristic allows identification of the separate servo bands. For example, the patterns of a separate servo band have differing azimuthal orientations of detectable transitions with respect to another servo band, such as being laterally inverted. In another, variations in the width of gaps of patterns are made with respect to another servo band. In another, variations are made in the number of the detectable transitions of patterns with respect to the patterns of another servo band.
