The first model was the TPS-L2. The most clarity on tape was the WMD6C in 1984 roughly 2 years before the discman came out and replaced the cassette tape forever. The first discman was the D-50 in 1986.

There has been over 300 different models to date. Many other companies copied Sony and made so very good competition for the walkman and the discman.
