Title: Multilayer film
Inventor: GOTO MAKOTO
IPC: F21V7/22
Filed: 1995-03-03
Abstract: PURPOSE: To provide a multilayer film constituted of a soft coat, and having good producibility and high durability. CONSTITUTION: This multilayer coat 6 is constituted by alternately laminating a high refractive index thin coat H composed of the thin coat of zinc sulfide containing 0.05-10wt.% of tin oxide, and a low refractive index thin coat L1 composed of the thin coat of magnesium fluoride, to form a soft coating film. Durability can be improved based on an estimated reason that effect, for preventing the oxidation of the zinc sulfide due to heat and the absorption of moisture, can be obtained because the tin oxide is contained 0.05wt.% or more; and a high refractive index can be obtained because the tin oxide is contained 10wt.% or less, thereby obtaining a large refraction index difference with the coat L1 in between. Consequently, a multilayer coat having high durable performance can be realized by the soft coating film under a condition where, in forming a coat, the possibility of generating a splash and so on and the necessity of a complicated manufacturing device and a process are eliminated, and also a manufacturing cost is not increased.

Title: Method of heat treatment for thin film magnetic head
Inventor: OKAMURA YUKO
IPC: G11B5/31
Filed: 1994-03-16
Abstract: PURPOSE:To give a high MR ratio to the magnetic material of an MR element and to give high magnetic permeability to the magnetic material of an IN element by forming the MR element and the IN element and then subjecting these elements to a series of heat treatment such as raising temp., maintaining the temp. and cooling. CONSTITUTION:Films are formed while a magnetic field of about 120Oe is applied with permanent magnets disposed on both sides of a substrate 1. The magnetic field applied on the films is decreased than the magnetic field for the MR element (about 170Oe) to prevent to give excessive anisotropy. The magnetic field applied is about 120Oe, because such conditions of heat treatment are required that if the more the anisotropic magnetic field is induced, the higher the temp. of heat treatment in the revolving magnetic field must be in order to improve the magnetic permeability. The IN lower magnetic pole 9 and upper magnetic pole 10 are formed as laminated films of SiAlON so as to suppress the reduction of magnetic permeability due to eddy current loss and movement of magnetic walls.
