43876CAN9A Disclosed is a method for reading or writing data on a tape which has a plurality of data tracks and at least a first dedicated servo track. A multiple channel head with at least three channels, each having at least one element for reading or writing, is used to access the tracks on the tape. The head is moved proximate one of a plurality of predetermined positions. The channels are located so that, in any one predetermined position of the head, one channel accesses the center of a dedicated servo track on the tape and at least two other channels will access the center of distinct data tracks. Depending on the predetermined position of the head, different channels will access a dedicated servo track. The position information on a dedicated servo track is used to move the head to one of the predetermined positions once the head has been moved proximate that predetermined position. 4:1.5
