Stereo Cassette Player (1983)
The development objective: "a Walkman® in the size of a cassette case." Key aspects of the design identity were diagonal control buttons and a clear rounded window that instantly revealed if a cassette was loaded. The battery compartment, heads, pinch rollers, and headphone jack were all arranged in a row as this component slid over when loading a cassette. To encourage a broader user base, the WM-20 was offered in several colors.
