Building a Magnetic Tape Recorder from Scratch, (1949-1952) by  Hans G. Mesch

The idea was to purchase a used recording head.   After a long time the AEG clerk returned to the desk and asked for the recorder model number.  We told him we had not assigned one yet.  When he found out that we were going to build a tape recorder from scratch he advised us to save our money because it had been unsuccessfully tried before. Twenty minutes later we left the AEG supply store with a 30.- DM used playback head.

The BASF ( Badische Annelin und Soda Fabrick) in Bavaria was the only company that produced this tape. But to purchase such a tape was another story!  Our first letter to BASF: Received no answer. Our second letter was answered: “ BASF only sells to radio stations and film studios.”  In our third letter we explained what we boys were trying to accomplish.  Someone at BASF must have had a heart because one month later, to our astonishment, we received a 1000 meter (3000ft) tape for the price of the 20.- DM.
