Abstract
An apparatus according to one embodiment includes a magnetic head having an array of transducers. An axis of the array is defined between outermost ones of the transducers. The transducers are arranged in at least two clusters of adjacent transducers, and the transducers in each respective cluster have about a same transducer pitch. A gap is defined between proximally adjacent clusters. A width of the gap measured along the axis of the array is greater than the transducer pitch of one of the clusters. An electrical lapping guide (ELG) located in the gap or aligned with the gap orthogonally to the axis.
