  • Method for manufacturing thin film magnetic head
    Patent number: 5715597
    Abstract: An improved thin film magnetic recording head includes a pole tip assembly which has a precisely formed physical geometry. The physical geometry of the pole tip assembly minimizes deleterious effects due to undershoots, while the method of manufacturing the pole tip assembly allows for precise control of feature tolerances (up to 0.2 micrometer accuracy) of the pole tip assembly. In one embodiment, the pole tip assembly has a generally hexagonal configuration with a raised hexagonal center portion comprising leading and trailing pole tips and a raised gap portion, and a surrounding hexagonal trench which surrounds the raised center portion. The raised center portion is substantially flush with the surrounding face of the recording head. Alternative embodiments contemplate elliptical or circular raised center portions, and variously shaped trenches to facilitate the evacuation of debris.
    Type: Grant

  • Thin film magnetic recording head for minimizing undershoots
    Patent number: 5675461
    Abstract: An improved thin film magnetic recording head includes a pole tip assembly which has a precisely formed physical geometry. The physical geometry of the pole tip assembly minimizes deleterious effects due roundershoots, while the method of manufacturing the pole tip assembly allows for precise control of feature tolerances (up to 0.2 micrometer accuracy) of the pole tip assembly. In one embodiment, the pole tip assembly has a generally hexagonal configuration with a raised hexagonal center portion comprising leading and trailing pole tips and a raised gap portion, and a surrounding hexagonal trench which surrounds the raised center portion. The raised center portion is substantially flush with the surrounding face of the recording head. Alternative embodiments contemplate elliptical or circular raised center portions, and variously shaped trenches to facilitate the evacuation of debris.
