The deviation of a tape from a linear path when transported across the heads, causing a time displacement between signals recorded on different tracks and amplitude differences between the outputs from individual tracks owing to variations in alignment.; 磁帶通過(guò)磁頭時(shí)相對(duì)于運(yùn)行路線的偏差,它會(huì)導(dǎo)致記錄在不同磁道上的信號(hào)的時(shí)差,以及 由于縱向彎曲而引起的各磁道輸出信號(hào)的幅度的差異。
