自研制成功RE120高效交流抹音头以来,我厂在大部分新设计的盒式录音机 (如L-400单声道四喇叭收录机;L-861台式立体声收录机)中均采用的此种抹音头。该抹音头效率高,将会在中高档盒式机上获得广泛的应用。本文主要介绍RE120高效抹音头的特点及磁头芯片成形工艺。 Since the successful development of the RE120 high efficiency AC head, our factory has adopted such erase head in most newly designed cassette recorders (such as the L-400 mono four-speaker recorder and the L-861 desktop stereo recorder) . The erase head efficiency, will be in the high-end cassette machine to obtain a wide range of applications. This article describes the characteristics of RE120 efficient head and head chip forming process.
