Abstract

See full text

The present invention is a truncated probe for a perpendicular recording write head. The truncated probe is formed in a resist using a pullback process. In the pullback process, a trench is formed in the resist. The resist is then heated to a required temperature for a predetermined duration of time. By controlling the temperature and time, the amount of pullback of the resist is controlled to form a specified angle for the truncated probe. Further, the present invention increases the efficiency of the write head by reducing the distance between the air-bearing surface (ABS) and a magnetic back gap of the perpendicular recording write head yokes. This reduction reduces the length of the write head and permits a faster rise time of a recorded signal.
