The main factor affecting the wavelength response is the non-magnetic spacing between the contacting surfaces of head and tape.
而影响波长响应的主要因素是磁头、磁带接触表面之间的非磁性间隔。

The magnetichead of a tape recorder.
磁头录音机中的磁头。

So the tape recorder which adopts this magnetichead can be used for wide band direct replay and makes signal-noise ratio improvement, it is an ideal playback head.
