Pocket Rockers

Pocket Rockers was a brand of personal stereo produced by Fisher-Price in the late 1980s, aimed at elementary school-age children. They played a proprietary variety of miniature cassette (appearing to be a smaller version of the 8-track tape) which was released only by Fisher-Price themselves. Designed to be as much of a fashion accessory as a music player, the devices were enough of a youth craze to even be banned in some schools for a brief period.
Housed in a variety of stylish, translucent colors, each tape had two songs in mono which could be clipped to clothing to showcase one’s musical taste. Tapes were available from several pop stars, including Michael Jackson, Whitney Houston, Tiffany, or Debbie Gibson and even rock stars like Bon Jovi or The Bangles. The commercials featured an original theme song which was a parody of "Down on the Corner” by Creedence Clearwater Revival.
In addition to standard blue on black and pink on black color schemes, 3 variations of Pocket Rockets were released utilizing Memphis Milano (a popular and contemporary design style at the time). A collectors set was released featuring one such design, and a deluxe system was also released which included speakers and a display stand with an amplifier. Other official Pocket Rockers branded accessories included bracelets, a bandana, a multitude of tape storage options (cases, frames, and clips), mini tape clip-ons, a carrying case, a purse, and headphones.
Following a sharp decline in sales, the Pocket Rockers line was discontinued in 1991 until ultimately being removed from Fisher-Price’s toy catalog in 1992. Today, the player and cassettes are sought after by collectors for their unique novelty and design.
Recording technology.
Inside the Pocket Rockers cartridge, the same 3.81 mm (0.150 Inch) tape like in the Compact Cassette is used, running at same tape speed of 1⅞ Inch per second. The upper two tracks contain one mono recording each, and the player has a switch that lets the listener change between the two available tracks. A small knob on the front controls the volume, and a headphone jack is on the side as well as a slider to eject the tape.
Winding the tape into a Compact Cassette, the recording is playing backwards. The lower two tracks were not used. The tape head is bottom top mounted Compact Cassette player head. The small endless tape cartridge based on a technology invented by Bernard Cousino is operated by a belt-driven capstan. Unlike standard cassettes, the pinch roller is part of the cassette rather than the player.
