Saphir: Digitizing broken and cracked or delaminated lacquer 78 rpm records using a desktop optical scanner

Abstract

We present an optical alternative for recovering the audio signal from analogue audio disc records that cannot be read mechanically. The new desktop-sized Saphir system uses simple components and allows scanning optically a 78rpm disc side in less than 30 minutes, still keeping a good signal-tonoise ratio over all the frequency range thanks to reflective principles. The process is far from realtime, but allows recovering the audio contents of even very much damaged records, that may otherwise be lost forever.
