The PXL-2000 is a black-and-white camcorder toy made by Fisher-Price in the 1980s that uses a normal audio cassette as its recording medium. The original designer at Fisher-Price was Andrew I. Bergman (1950-2007).
You can use any normal audio cassette tape to capture both audio and video. A 90 minute cassette-tape holds 11 minutes of video at high speed. This speed is necessary because video requires a wider bandwidth than standard audio recording. In magnetic recording, the faster the recording speed, the more information can be stored on the tape. The PXL-2000 records the video information on the left audio channel of the cassette, and the audio on the right.
Already since the 1990s, the PXL-2000 cameras has seen a revival in popularity and is cultivated among independent and experimental video makers, artists and designers due to its unique low-resolution pixelated black/white image, with a lower frame rate of around 15 frame/s, akin to 8mm or super-8 movie film (upconverted to the standard 30 frame/s in the camera). The image is also 'windowboxed', meaning it has a black border around all sides of the picture.
PXL-2000 cameras are still popular in the (underground) film making scene with some individuals offer repairs and modifications for the PXL-2000 to output composite video (the PXL-2000 only has an RF output selectable to either North American television channel 3 or 4 in its unmodified stock condition), to interface to an external camcorder with a composite video in, or a VCR. The cameras are still very popular, fetching prices as high as $100 to $500 on eBay.
