Abstract
A magnetic write head arranged to maximize efficiency of an optical device used to locally heat a magnetic medium during use, also to maximize efficiency of a heater element for thermal fly height control. The magnetic head is constructed with a read head, a write head and a slider body. The write head is located between the read head and the slider body. A heater element can be located between the read head and the write head and an optical device such as an optical waveguide can be located between the write head and the slider body. The write head can be constructed to have a write pole that is closer to the slider body than the return pole is, thereby allowing the write pole to be adjacent to the optical device.
