Master sound recording discs for gramophone record mfr. - where recording is cut directly into a metal or alloy disc

The master disc is pref. made of an alloy of non-ferrous metals, esp. using tin, lead, aluminium, silver, copper, and/or indium. Improves the fidelity of the recording and also simplifies the complicated series of operations normally involved in the plating processes used for record mfr. Master discs are usually made using a thin disc of aluminium coated on both sides with a lacquer, in which the recording is cut using a stylus surrounded by a small heater coil which facilitates cutting, but the heat alters the plasticity of the lacquer and the fidelity of high-frequency signal recording. By using a metal or alloy disc with no lacquer, the dimensions of the cutter stylus can be chosen so no heater coil is required, and fidelity is improved together with the signal/noise ratio. The metal disc can be cut with a diamond cutting stylus and reduces the number of plating operations normally employed in the electroforming of the stamping negatives used to press records.

Improvements in or relating to apparatus for driving gramophone records

336,684. Harris, A. W. July 23, 1929. Securing flywheels on shafts.-In the trans mission train from a prime mover to a gramophone turntable, a massive element smoothes out the relatively small vibratory variations in the driving effort by the effect of inertia and a resilient coupling smoothes out the relatively large vibratory variations, the resilient coupling being rigid when transmitting torques below a given amount. The drive from the prime mover is transmitted by a worm 3 and worm-wheel 4. The latter has two pins 5 passing through arcuate slots 6 in a flywheel 1. The upper face of the flywheel 1 has a circular channel 7 in which two pairs of blocks 8 are slidable, the blocks of each pair being forced towards one another and against stops 9 on the flywheel 1 by springs 10. The end of each block 8 adjacent each pin 5 has a semi-circular recess to clear the pins. For torques below a given amount the coupling transmits solidly, the blocks 8 remaining hard up against the pins 5. When the torque increases above the given amount the normal tension of the springs is exceeded and the coupling becomes resilient.
