| Abstract(in English) | Perpendicular recording heads capable of strong recording field and high field gradient for higher recording densities were studied by field analysis. If a current density beyond 10^9A/cm^2 is available for a recording coil of the head, the head structure such that an additional yoke is placed within a distance of lOOnm from the main pole and a coil conductor is formed in between them can provide superior head field. The reason is as follows. The coil can be small enough to produce a large magnetic field and it locates close to the main pole tip at the air-bearing surface. So, a coil field itself with a large strength can be created at the recording layer of the medium. In this design concept, narrowing trackwidth for higher recording density is preferable because smaller coil size could produce larger field strength. |
