ABSTRACT:
A data-track head-positioning servo system is disclosed. Data tracks are used to provide position and reference information to a straddle servo head and a reference servo head. The reference servo head provides a reference signal against which the servo signal from the straddle servo head is compared to correct for alignment errors. A transducer head having an integral data transducer, the reference servo transducer, and straddle servo transducer in a fixed spacial relationship is disclosed. A method for using the transducer head in a multitrack tape system is also disclosed.
