众所周知,当磁带在录音机磁头表面上通过时,除了在磁带和磁头之间交换已录的信息之外,在效果上好象是长时间用细纱纸打磨木头块。象木头一样,磁头表面逐渐受磁带的作用而磨损。这个过程的最初效果是抛光磁头表面。这会略微改善磁头的高频性能,不过在很大程度上首先取决于磁头的状况。如果象许多现代磁
It is well known that when the tape passes over the head surface of the recorder, it appears as if it is time to polish the block of wood with the tissue paper, in addition to exchanging recorded information between the tape and the head. Like wood, the surface of the magnetic head is gradually worn by the tape. The initial effect of this process is to polish the surface of the head. This slightly improves the high-frequency performance of the head, but first and foremost depends on the condition of the head. If like many modern magnets
