Measurement of wow and flutter is carried out on audio tape machines, cassette recorders and players, and other analog recording and reproduction devices with rotary components (e.g. movie projectors, turntables (vinyl recording), etc.) This measurement quantifies the amount of 'frequency wobble' (caused by speed fluctuations) present in ...
The thickest tape normally used in cassettes is about 16-18 μm in thickness, and is used in C60 cassettes and in shorter lengths such as the C46. As the standard tape speed for a compact cassette is 1 + 7 ⁄ 8 inches per second (4.762 cm/s) and a C60 cassette records 30 minutes per side, a C60 cassette in theory holds 281 + 1 ⁄ 4 ft (85.73 ...

It is caused by imperfect bearings, uneven motor windings, vibrations in driving bands in some turntables, room vibrations (e.g., from traffic) that is transmitted by the turntable mounting and so to the phono cartridge.
