Description (Brief)
This unusual magnetic recorder was used an a dictation machine in the 1960s. The recording medium is a letter-sized sheet coated with a magnetic powder. The round plate on the machine carried the read-write head and spins under the stationary sheet. One can then fold the recording and mail it to the recipient. The donor’s father owned a business equipment store and acquired this piece as a marketing demonstration. In this instance, the product did not succeed in the market.
