摘要： Methods and apparatuses for writing spiral servo patterns on a disk surface are disclosed. In one embodiment, a method is provided to write servo information onto a disk surface in spiral patterns in a non-sequential manner. In another embodiment, a thermal warm-up regimen is performed prior to writing spiral patterns onto the disk surface. In another embodiment, a reference track is used to position a write head when writing spiral patterns onto the disk surface. By using one or more of the above embodiments, the affects of thermal and/or mechanical changes may be reduced when writing spiral patterns.

摘要： A method and apparatus for writing spiral servo information is provided. In one embodiment, a servo track writer having a digital signal processor is provided. The servo track writer also includes a clock head, which reads a clock track from a disk surface to generate a clock signal that is used to provide interrupt signals to the digital signal processor. A transducer, which writes spiral servo information onto the disk surface, is positioned under control of the digital signal processor based upon the interrupt signals. In one embodiment, a method of writing spiral servo information onto a disk surface using a servo track writer having a digital signal processor is provided. The method includes the steps of reading a clock track written onto the disk surface to generate interrupt signals; providing the interrupt signals to the digital signal processor; and, positioning a transducer over the disk surface under control of the digital signal processor based upon the interrupt signals provided thereto.
