在记录数字的磁带机上,实用最大脉冲记录密度的计算方法,一般都不清楚。在这类机器上,信息一般都是平行地记录在横跨于磁带的几个磁道上。通常,在1/2时宽的带上记8道,在1时宽的带上记16道。磁带总是与磁头接触的,并采用不归零制(没有变化或一次磁通翻转代表一个二进位数)。 In the recording of digital tape drives, the practical maximum pulse recording density is generally not clear. On such machines, the information is usually recorded in parallel on a few tracks across the tape. Normally, record 8 tracks on the ½ hour wide track and 16 tracks on the 1 hour wide track. The tape is always in contact with the head and is not zeroed (no change or a flux flip represents a binary number).
