Indeed, there was a lot of different tape cassette formats in the 60's before Philips' "compact cassette" finally was adopted as a worldwide standard. But even before that, attempts were made, in particular by japanese companies, to make cheap, portable open reel tape players.
Besides ordinary magnetic tape cassettes, there were also systems that used a mechanical groove in a PTFE (teflon) tape, that was played back by a needle and pickup like a vinyl record. For instance, the "Tefifon" that was manufactured by a german company, Tefi. |
