=Compare / Contrast Sony Walkman / Discman / iPod=

Sony Walkman
The Walkman is a mechanical device which plays back magnetic cassettes. The controls are also mechanical and are spring loaded. A tape head plays back the analogue cassette, and rewinding or fast forwarding requires the spindles to actually spin the tape to the correct location. A major drawback of this technology is the tape stretches and wears out after x amount of uses.

Discman
The Discman is similar to the Walkman, except it uses compact discs instead of cassettes to playback the audio. Aside from the difference in the medium used, the Walkman is analogue while the Discman is digital. Both devices are mechanical since the need to physically spin the media. The discman uses an optical laser to play the digital audio from the disc. A major drawback of this technology is it is prone to skipping, and the cd media itself is prone to scratches.
