An apparatus in a dual actuator disk drive system having a nonpackwriting actuator (9) and a packwriting actuator (8) for controlling the sensing of address marks by the transducers (13, 23, 24, 26, 28 and 30) associated with the nonpacking actuator after a switching operation between any two of the transducers (13, 23, 24, 26, 28 and 30) associated with the nonpackwriter actuator (9). The apparatus comprising an address mark means (48) for generating an address mark search signal to start an address mark search when an address mark is expected to be read by the presently selected transducer (13, 23, 24, 26, 28 or 30) associated with said nonpackwriter actuator (9) and an adjusting means (52, 49) connected to said address mark means (48) for altering the time when said address mark means (48) will generate said address mark search signal such that the newly selected transducer (13, 23, 24, 26, 28 or 30) will read the next address mark to occur on the track being read by the newly selected transducer (13, 23, 24, 26, 28 or 30) after said newly transducer (13, 23, 24, 26, 28 or 30) has been selected. |
