Abstract

This thesis investigates the possibility of increasing the storage capacity of a rigid disk using a variable velocity Brushless DC motor. An introduction is made to the two major disk storage systems: floppy disk drives and Winchester disk drives. A tutorial is presented on the various constraints imposed on information storage by these two systems. Fixed speed is the constraint focused on and the remainder of the study investigates the possibility of lifting this constraint. A computer simulation utilizing Boeing's EASY5 simulation program is used to model and simulate a Winchester disk storage system using a Brushless DC motor as the spindle drive. Observations are made on system performance, system limitations, and suggestions on areas that require future investigation.
