Magnetic Disk Recorder

Description (Brief)
This Brush “Mail-A-Voice” recorder was designed in the late 1940s as an office dictating machine. As tape recording technology was developed, experimenters tried a variety of formats including flat paper or plastic discs. These discs resembled the record players familiar to many in that era and did not require threading a wire or tape. The discs could also be folded and mailed to a recipient in an ordinary business-size envelope, something impossible to do with an inflexible record.
