摘要 |
PCT No. PCT/FR91/00557 Sec. 371 Date Feb. 28, 1992 Sec. 102(e) Date Feb. 28, 1992 PCT Filed Jul. 10, 1991 PCT Pub. No. WO92/02015 PCT Pub. Date Feb. 6, 1992.Process for producing red and/or write heads for magnetic recording. According to the invention, use is made of a monocrystalline substrate (16), which is anisotropically etched in accordance with a crystallographic plane in order to give the gap (48) its precise direction (straight or inclined). The substrate also undergoes thermal oxidation to give the gap a given thickness. Application to heads for video recording. |
