PlayTape

PlayTape is an 1⁄8 inch (3.2 mm) analog magnetic tape format which runs at 3¾ i.p.s., has a frequency range of 50 Hz to 8kHz, "the same as most AM radios or TV sets" of the day, approximately the same track widths and spacing as standard 4-track systems, and which featured monaural playback. Introduced in 1966 by Frank Stanton, it is a two-track system, and was launched to compete with existing 4-track cartridge technology. The tape cartridges play anywhere from eight to 24 minutes, and are continuous. Because of its portability, PlayTape was an almost instant success, and over 3,000 artists had published in this format by 1968. White cases usually meant about eight songs were on the tape.
