Material for nonmagnetic oxide substrate and magnetic head |
March 1, 1994 |
| A nonmagnetic oxide substrate material has a composition of 15 to 60 mol % of NiO, 10 to 70 mol % of CoO, 10 to 40 mol % of TiO.sub.2, and 0.5 to 25 mol % of CaO and is formed of very minute crystal grains. Preferably MgO or ZrO.sub.2 is used as an additive to the material to present a t |

Thin film magnetic head and method of manufacturing the same |
October 9, 1984 |
| A thin film magnetic head is composed of a first thin film of a magnetic material deposited on a non-magnetic substrate. A V-like groove is formed in the first magnetic thin film with a depth reaching the non-magnetic substrate. One wall face of the V-like groove is deposited with a |
