The first digital microcassette recorder, used with postage stamp-sized cassettes developed by Sony. These cassettes were certified as the world’s smallest tapes for digital recording in the 1994 edition of the "Guinness book of world records." The NT-1 represented all that a portable tape recorder should be. This light and compact unit offered excellent sound quality, extended recording, and good energy efficiency. Built around the microcassette layout, it was designed for easy one-handed operation. In appearance, the “Scoopman” is appealingly simple.
