磁头是磁性录音中的电、磁换能器,是磁带录音机的关键部件之一。磁头的各项电磁性能都将直接影响录音机的主要技术指标。将经过录音放大器的音频电信号输给磁头,在磁头的缝隙中将产生幅度比例于音频电信号的磁场,磁化以匀速通过磁头缝隙的磁带,音频电信号最后以剩磁的形式保留在磁带上,这就是录音机的录音过程。此时的磁头起 Magnetic head is a magnetic recording of electricity, magnetic transducer, tape recorder is one of the key components. Head of the electromagnetic properties will have a direct impact on the recorder’s main technical indicators. The audio amplifier through the audio signal to the head, the head gap will produce amplitude proportional to the magnetic field of the audio signal, the magnetic uniform magnetic head gap through the tape, the final audio signal in the form of residual magnetism on the tape This is the recording process of the recorder.
