| titleOfInvention | Servo control of tape drives |
| abstract | There is provided a servo control method and apparatus for a tape drive 1 for reading and writing data on a magnetic tape 3 having at least one servo track for the read / write head 2 to provide horizontal position information . At least two servo readers S are associated with the read / write heads 2, each arranged to read the servo tracks during a read / write operation. The servo reader S operates simultaneously to generate the respective servo read signals r. The position estimator 8 processes each servo read signal r to generate a series of position values corresponding to each time, which indicates the lateral position of the associated servo reader S. [ The servo controller 10 determines from the position values and times the skew value (< RTI ID = 0.0 > ), And a tension variation value (" ). The servo controller 10 is adapted to consider the cross coupling between the tape skew and the tension variation in the joint calculation of the skew value and the tension variation value. When three servo readers S operate at the same time, the servo controller 10 calculates the skew value and the tension variation value ) For each time derivative ( ). ≪ / RTI > The calculated values can then be used to make tape skew to the read / write head 2 and compensate adjustment to tape tension. |
