ABSTRACT:
A magnetic recording disk drive uses side-by-side read/write heads formed on head carriers that are substantially identical for both top and bottom disk surfaces. Thus, a common head carrier functions as a single manufacturable part usable for both top and bottom disk surfaces. The common head carrier has a trailing end with a pattern of components formed on it that includes three side-by-side transducers and sets of terminal pads. In the read/write/read side-by-side head arrangement, the first element is a center write element, such as an inductive coil, and the second and third elements are read elements, such as magnetoresistive read elements, that are generally equally spaced from the center write element. In common carriers to be used for the top disk surfaces, one of the read elements is electrically connected to the read/write channel of the disk drive, and in common carriers to be used for the bottom disk surfaces, the other read element on the common carrier is electrically connected to the read/write channel. The disk drive thus operates in cylinder mode with side-by-side heads using a common carrier for both top and bottom disk surfaces.
