The National Library Service for the Blind and Physically Handicapped (NLS/BPH) began distributing magazines and books on flexible discs running at 8⅓ rpm in the early 1970s in the US. Machines capable of playing this very slow speed had already been made available a number of years previously when model AE-1 was introduced in 1965, and existing machines were also converted by volunteers. Standard ‘rigid’ records running at 8⅓ rpm had been available via the NLS/BPH since 1969.
Magazine titles available included Readers Digest, National Geographic, Sports Illustrated, and U.S. News & World Report.
The flexi-discs were 9-inches in diameter and had Braille centre labels. They also had narrower grooves than a standard record, so a finer stylus is required to avoid damage. The use of a slow speed and fine grooves allowed very long playing times, but lower fidelity. The discs could be produced quickly and cheaply, meaning audio magazines could be distributed as soon as possible after the print copy. Their success meant the NLS/BPH stopped using rigid records by the late 1980s.
After 1994, audio magazines on flexible disc began to be phased out in favour of Compact Cassettes, and the final discs were sent out in 2001.
