ABSTRACT OF THE DISCLOSURE A compact cassette tape player has a motor drive system which enables a high-fidelity tape player to be made only slightly larger than the cassette being played. The tape player includes a motor which has a flat stator mounted to the player chassis, a motor shaft and a flat rotor which is mounted to the motor shaft for rotation relative to the stator. The recorder includes reel spindles for engaging the tape reels in the cassette. The motor shaft extends into one of the spindles and is mounted in bearings at the ends of the shaft. One of the bearings is located inside the spindle so that the bearing mountings for the rotor shaft can be spaced as far apart as possible, thus reducing the amount of wow and flutter even though the player is extremely compact. The spindle mounting the motor shaft is driver. independently of the motor by a drive gear which engages the periphery of a gear wheel secured to the spindle. The drive gear is driven by a drive belt which extends from the motor rotor to the player capstan.
