在人们的生活、学习、工作中会需要对传送的音频信号实现长时间连续记录。然而目前的录音机即使是用长记录时间的C120录音磁带,装入一次(不翻面)也只能记录1小时。显然,采用现有的普通录音工具和录音方法是难以再延长录音时间的。 In people’s lives, learning, work will need to send the audio signal to achieve long continuous record. However, even if the current recorder is equipped with a C120 recording tape which has a long recording time, it can record only for one hour (without turning over). Obviously, it is difficult to prolong the recording time with existing common recording tools and recording methods.
