伺服信息可记录在一个专用的盘面上。也可和数据一起记录在同一盘面上。伺服数据和工作数据交叉排列的称为扇区伺服。伺服信息和数据分别记录在介质的内层和表层的称为分层型伺服。同时采用伺服扇和伺服面进行定位有助于消除低频偏摆;N-Q区交错的TRIBIT格式可使道密度加倍;改进的N-Q区交错型伺服允许磁头偏移量大于1/4道间距。本文提供的电路简单实用。
Servo information can be recorded on a dedicated disk. Can also be recorded together with the data on the same disk. Servo data and work data cross-arranged called sector servo. Servo information and data recorded in the media, respectively, the inner and outer layer called servo. Positioning with both servo fan and servo face at the same time helps to eliminate the low-frequency yaw. The staggered TRIBIT format in the N-Q region can double the channel density. The improved N-Q region staggered servo allows the head offset to be greater than 1/4 track pitch. This article provides a simple and practical circuit.
