Digital vs. Analog

Mp3 vs Tape


The MP3 player is the most recent in an evolution of music formats that have helped consumers enjoy their tunes. Records, 8-track tapes, cassette tapes and CDs -- none of these earlier music formats provide the convenience and control that MP3 players deliver. With an MP3 player in hand or pocket, a consumer can create personalized music lists and carry thousands of songs wherever they go.


The cassette actually predated the 8-track by about a year, although it was cheap children's technology through the late 1960s. This small, two-reel cartridge was introduced by Phillips in Europe and Norelco in the U.S. It was based on, but intended for a different market than a similar small cartridge system that Phillips introduced for office dictation purposes. The "Carry-Corder" battery operated recorder/player made low quality recordings in mono only, but once prices for the recorders came down it proved to be a huge hit with teens.
