目前国内广播系统中录音机进口数量不少,但备用元器件很少,尤其是主要元件如录音磁头磨损,音质下降,不能使用。针对这种情况,我们在研制进口甲级录音机磁头的同时,对进口磨损的旧磁头进行了修复,这样不但可以节约资金,而且见效快。 At present, there are quite a few importers of voice recorders in the domestic broadcasting system, but there are few spare components, especially the wear of the main components such as the recording head, the drop of sound quality, and the inability to use it. In response to this situation, we developed the import of Class A head recorder at the same time, imported wear and tear of the old head was repaired, so that not only can save money, but also quick.
