An Experimental Model of Sled System in an Optical Disk Drive

Abstract

The influence of the neutron-neutron off-energy-shell interaction on the extraction of ann in p -d capture has been discussed. An analysis has been perfonned for several relative neutron-neutron angles and it has been found that the off-shell uncertainty increases w i t h the angle.

A Survey of Control Issues in Optical Data Storage Systems

“…The jumping accuracy can be remarkably increased with the micro-stepping technique of a stepper motor, while the motor is more expensive than a DC motor. In the case of a DC motor-based sledge, the calibration of friction is crucial to enhance the jumping accuracy (Han et al [2000], Hsu and Fu [2004], Helwegen [2005]).…”
