| 术语 | gap loss |
| 释义 | gap loss 间隙丢失,间隙损耗 1. In magnetic disk recording, the loss of signal because the reading head is not directly in line with the information recorded. 在磁盘记录过程中,因为读入头与记录的信息没有对准而产生的信号丢失。 2. The loss in output attributable to the finite gap length of the recording head. The loss increases, as the wavelength decreases, amounting to approximately 4dB when the wavelength is equal to twice the gap length, and subsequently increases rapidly towards a complete extinction of output when the wavelength is equal to approximately 1.15 times the gap length. 由于记录磁头间隙长度有限引起的输出损失。这种损失随波长的缩短而增加,当波长 等于间隙的二倍时,约为4dB;当波长约为间隙长度的1.15倍时,输出迅速减至零。 |
