ABSTRACT:
In a disk drive system having two actuators, each said actuator having a plurality of transducers, said system employing a transducer switching procedure for switching between a first presently selected transducer and a second to be selected transducer, an apparatus, associated with the nonpackwriting actuator, for controlling the sensing of an address mark by said second transducer, said apparatus comprising an address mark means for generating an address mark search signal to start an address mark search when an address mark is expected to be read by said first transducers; and an adjusting means connected to said address mark means for altering the time when said address mark means will generate said address mark search signal such that said second transducer will read the next address mark to occur on the track being read by said second transducer after said second transducer is selected.
