ABSTRACT:
A supply spindle for a cassette recorder which includes means for reducing the abrupt start-up forces to which the recording tape within the cassette is subjected by incrementally coupling the inertial mass of the supply spindle to the tape upon start-up. The supply spindle includes a shaft carrying a supply head for engaging a cassette spool. The supply head is axially as well as rotationally movable upon the shaft. A coil spring, fixed to the shaft and supply head, urges the head to the end of the shaft. Additionally, the spring rotatably biases the supply head against a stop carried on the shaft. Initially upon start-up, only a portion of the mass of the supply spindle is coupled to the magnetic tape with the full mass being subsequently coupled thereto.
