| Abstract: | An audio recording/playback head using an amorphous (Fe-Co-Ru-Cr) 75(Si-B)25 alloy was developed. Compared with a commercial Sendust head, three excellent features were observed. The wear of the amorphous alloy head when used with γ-Fe2O 3 is two-thirds that of the Sendust head. The output level at high-frequency (14 kHz) is 5 dB higher than that of the Sendust head. The bias current for the amorphous alloy head is half that of the Sendust head |
