在磁盘上产生磁参考式样的方法及装置

Method and device producing magnetic reference sample on magnetic disk

Abstract

The present invention provides a method of generating magnetic reference patterns on a disk or other magnetic media. This involves writing a first magnetic reference pattern to the disk with a servo writer. The disk may then be transferred to a hard disk drive. Control circuitry within the hard disk drive may recognize the first magnetic reference pattern and then position a RW head within the hard disk drive based on the first magnetic reference pattern. As the RW drive is accurately positioned based on the first magnetic reference pattern a second magnetic reference pattern may be written to the disk using the RW head. The RW head location is determined based on the velocity and phase between the read-write head and servo setter marks contained within the first magnetic reference pattern.
本发明提供一种在磁盘或其它磁介质上产生磁参考式样的方法,包括首先使用伺服写录器将第一磁参考式样写录到磁盘上,接着将磁盘转移到硬盘驱动器中。硬盘驱动器中的控制电路能识别出第一磁参考式样,并基于第一磁参考式样确定硬盘驱动器内的读写头的位置。因为读写头是基于第一磁参考式样来精确定位的,因此可使用读写头将第二磁参考式样写录到磁盘上。读写头的位置是基于读写头与包含在第一磁参考式样中的伺服定位标记之间的速率和相位而确定。
