Thin-film magnetic head having a recording head portion configured to record magnetic information on a patterned media, head gimbal assembly, and hard disk system |
摘要 |
The invention provides a thin-film magnetic head wherein the combined release angle Φ for a dominant recording magnetic field generated from a magnetic pole layer toward a patterned media for the purpose of recording magnetic information is set to within an angle range of 35° to 65° with respect to a patterned media surface. It is thus possible to invert, with efficiency and reliability, the directions of magnetization of isolate bits lined up on the patterned media for high-density recording.
