This reel-to-reel BK-401 “Soundmirror” used paper recording tape coated with artificial magnetite particles. Brush Company designed the BK-401 after Semi Begun’s experiments convinced him that a thin, flexible tape would give good audio performance. Introduced in 1947 with tape made by Shellmar Company, the expensive BK-401 malfunctioned easily. Despite good initial sales, production ceased in 1952.
