High Track Density Graphic Head Positioning Method
1994
Journal of the Magnetics Society of Japan
Preserved Fulltext
To minimize the restriction of conventional servo method, a new method used graphics for head positioning have been investigated. This paper will describe the principals of graphical construction and encoding, servo demodulation, and performance evaluation of graphics, etc. Finally for verifying this method, a 4000 TPI track density trial device is introduced.
