ABSTRACT:
A carriage movement device for a magnetic memory device having a carriage with a first end and a second end, the carriage being slidably supported on a rod is provided. The carriage movement device has a capstan which is angularly rotated by a driver and a belt having an elongated slot extending form a portion of the belt having the second width, the slot being at least as wide as the first end wrapping around the capstan. A first belt connector connects the first end of the belt to the first end of the carriage. A second belt connector connects the second end of the belt to the second end of the carriage. The second end of the belt is affixed to a second belt connector which is selectively engaged to the second end of the carriage by stretching the belt about the carriage and or deflecting an elastic projection formed on the carriage. The angular rotation of the capstan is accurately converted into linear movement of the carriage.
