From http://great78.archive.org/preservation/: "During the 78rpm era there are no standards for speed, stylus size, or record/playback equalization. Within the trade there is broad agreement that optimizing playback requires both knowledge of the documentation that’s available on these parameters for each label over time, and some amount of judgment. There are many reasons why judgment is necessary. One reason is that the disc may be worn from being played many times with the correct stylus size. Better results may come from using a different (“the wrong”) size stylus because it sits in a portion of the groove that is in better condition. But there’s no free lunch. Using a smaller size may mean a noisier transfer as it plays a less cleanly molded part of the disc. Using a larger size may increase tracing distortion that is the result of the larger size not fitting all the way to the bottom of the smaller grooves of higher frequencies. [...]" |
