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.

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： A method for transferring corrected data to an external buffer within a tape drive is provided. After the receipt of data from a data recording medium, the data are stored in an external buffer. The data are then transferred from the external buffer to an error correction code (ECC) device. Any error in the data within the ECC device are corrected. The corrected data are subsequently divided into multiple sub-units, and a transfer flag is added to each of the sub-units having corrected data. Only the sub-units having corrected data are transferred from the ECC device back to the external buffer.
