GRAY AUDOGRAPH RECORD
GRAY AUDOGRAPH record transfe to audio file: $45 per disk. Complete pricing below.
Gray Audograph records were introduced by the Gray Manufacturing Company of Hartford Connecticut in 1945 for recording audio dictation. Gray Audograph disks are blue flexible grooved disks with a star center hub. They play with a constant speed under the needle that is achieved by rotating the disks with a variable rotational speed of approx. 33 rpm to 15 rpm starting from the center and playing outward towards the edge. The needle is fixed and the record platter rotates and slides with an intricate mechanical design. The spacing between the record grooves is approx. 0.100mm (0.004-inches). Disks can be "resurfaced" to remove the groves and can be reused. Soundwriter machines will record and playback 20, 30, and 60-minute disks. Other names associated with this format are Gray Flexograph, Gray Transcriptions, Electronic Sound Writer, Gray Audograph, and Phonaudograph.
