Magnetic Recording Disks

Description (Brief)
These recording discs were made for the Brush Company “Mail-A-Voice” dictating machine. This set of 62 discs includes several slightly different types, the most significant difference being that some are paper and some are plastic. All are flexible and coated with a magnetizable powder. The Mail-A-Voice was designed by German immigrant Semi J. Begun who also used the device for personal correspondence. Several of the discs in the set are audio letters from Begun to his mother.
