Latest Patents

Kuwatsuka's latest patents include a method of fabricating a thin-film magnetic head. This method involves forming a mask pattern in etching a bottom pole using first and second mask films. The first mask film is utilized for defining, by self-alignment, the length of the side edge of a top pole that is nearly perpendicular to a magnetic gap. The second mask film allows for high dimensional accuracy in etching the bottom pole. Additionally, a non-magnetic film is formed on the mask pattern, and the top pole is created after the mask pattern has been exposed and removed. Another notable patent is for a magnetic disc apparatus with a thin film head suitable for high-density applications. This apparatus includes a magnetic disc for recording information and a thin film magnetic head with a magnetic pole structure designed for efficient writing and reading of information.
