Answer 1

In a cassette player, a magnetized tape runs past a detector which converts the magnetic signal into an electrical signal, which gets fed straight into the speaker to produce sound.

A CD player does normal CD player stuff, but instead of a speaker it has a small electromagnet right by the cassette reader, so the electrical signal turns into a magnetic signal which the reader then picks up normally.
