Abstract
A carriage assembly has a carriage provided on both sides with voice coils, a magnet assembly surrounding the voice coils and adapted for causing the carriage to move in the radial direction of a disk, and guide rails for guiding the carriage in the radial direction of the disk. The carriage is provided on a lower portion thereof with first rollers for engagement with the guide rails and at its upper portion thereof with second rollers which co-operate with a biasing members in preventing the carriage from moving upward. Either the guide rails or the first rollers are provided with grooves which prevent the first rollers from moving in the tangential directions of the guide rails. Since the movement of the first rollers in the tangential directions of the guide rail is prevented, it is possible to locate the carriage with a high degree of precision with respect to the disk.
