摘要
A record and turntable assembly featuring precise and repeatable angular and linear positioning of the record on the turntable, and positive rotary drive. The turntable is provided with three conically tapered mounting pins projecting from the surface and arranged in a scalene triangular array. The record is formed with matingly tapered mounting holes arranged in a congruent triangular array, so that the record and turntable can be assembled by placing the record on the turntable with the holes received on and engaging the pins. This provides a positive drive between the turntable and record, and assures the desired, repeatable angular and linear positioning of record on the turntable.
