前言为提高磁性录音机的性能研制了PCM录音机,现已经过10几年的时间。迄今研制的PCM录音机大致分为两种:一种是旋转磁头方式,使用VTR的走带系统;另一种是固定磁头方式,走带系统与模拟录音机相同。虽然这两种方式各有其优缺点,但固定磁头方式使用起来有与模拟录音机相同的感觉,同时可以进行监听和人工编辑,这些优点是旋转磁头方式所不具备的,所以将来会成为原版录音机的主流。
Preface To improve the performance of magnetic tape recorders developed PCM recorder, it has been 10 years time. PCM recorders developed to date are broadly classified into two types: one is a rotary head method, a tape transport system using a VTR, the other is a fixed head method, and the tape transport system is the same as an analog recorder. Although each of these two methods has its own advantages and disadvantages, the fixed head method uses the same feel as the analogue recorder and can be monitored and edited at the same time. These advantages are not available with the rotary head method, so it will become the original recorder The mainstream.
