IPC: G11B5/127
Filed: 1990-07-13
Abstract: PURPOSE:To improve productivity and performance by using a ceramic substrate essentially consisting of alpha-Fe2O3 as a nonmagnetic substrate to improve the wear resistance thereof. CONSTITUTION:The ceramic substrate consisting of the alpha-Fe2O3 having high hardness is used as the nonmagnetic substrate 1. An interlayer material 2 consisting of forsterite is formed at a prescribed film thickness by means, such as sputtering, on this nonmagnetic substrate 1. A lower magnetic core 3 is formed at a prescribed thickness by means, such as sputtering, on the interlayer material 2. Since the tape sliding surface of the head is mostly the substrate surface, the wear resistance is improved by enhancing the hardness of the substrate 1. The gap depth is decreased in this way and the performance is improved. The core thickness of the thin-film magnetic head is reduced as well, by which the productivity is improved.
