| Popis: |
A novel magnetic head with thin-film magnetic yokes and thin-film coils for VCR systems has been developed. The head has 25- mu m-thick CoNbZr (B/sub s/=0.9 T) magnetic yokes with round edges. The lower yoke is buried in the groove with a round bottom formed by a combination of photolithographic and mechanical processing, while the upper yoke is formed by ion etching. The head with a 150 mu m gap depth has excellent recording performance on high H/sub c/ media (H/sub c/=1500 Oe). Its contour-signal level is below -45 dB from the main signal ( lambda =2.5 mu m). > |
