It turns out that cassette tape is made of a thin plastic layer, which holds a layer of ferric oxide. To put it another way, cassette tapes are using a material related to rust. Being a ferromagnetic substance, ferric oxide stores a magnetic field we expose it to. Please see a detailed explanation in the link.
