4000TPI光刻面伺服系统的高速寻道机理

High Speed Seek Mechanics of 4000 TPI Etched Surface Servo System

光刻伺服盘是一种新的磁头伺服定位技术［１］，通过对４０００ＴＰＩ光刻面伺服系统的光刻伺服图形结构的分析，本文提出了一种简单可靠的磁头过道脉冲检测方式，可显著提高磁头寻道速度，保证磁头在高道密度下高速寻道。

Etched servo disk is a new magnetic head positioning technique.In this paper.a novel magnetic head crab track pluck detection way is given by the analysis of etched servo graph for 4000 TPI etched surface servo.It improve the maximum seek track speed of magnetic head greatly, So that magnetic head can seek track at high speak for high track density.
