Abstract

Comprehensive experiments and analysis were conducted on SONY CD-ROM drives to derive a model of the sled system, with an emphasis on dynamic analysis of sled friction. Our study featured a novel method of friction analysis, in which all the measurements were conducted in transient period and all the calculations were transferred from the time domain to the velocity domain, and a new concept of elastic effect in sled systems, which gave a reasonable explanation of the oscillatory phenomenon in sled movement. The simulation results based on the derived model agreed well with the experimental data and repeated comparisons revealed the model's reliability. This confirmed the model's practicability in developing high-performance sled servos and track jump controllers.
