THIN FILM MAGNETIC HEAD AND MULTICHANNEL THIN FILM MAGNETIC HEAD

摘要

PURPOSE: To decrease uneven wear of the sliding surface of a head to a magnetic recording medium, to suppress reduction of head output and recording efficiency due to spacing loss, and to largely improve the life of a head. ;CONSTITUTION: This thin film magnetic head has a closed magnetic circuit produced by the lower magnetic core 1 and the upper magnetic core 2. At least one of the magnetic cores 1, 2 consists of a laminated film obtd. by alternately laminating intermediate layers 11, 11b, and metal magnetic thin films 12a, 12b.;COPYRIGHT: (C)1994,JPO&Japio
