El Casete

Philips's compact tape: the recordable music that fit in a pocket

Presented by Philips in Berlin in 1963, the compact cassette put recording within anyone's reach. In the Venezuelan minitecas it was the medium of the jingles — Sonotek, Magnum and TDK tapes carrying the voices of the great announcers — and of the tapes that were treasured and resold; with the Walkman (1979), on top of that, music became personal.

What the cassette is

The compact cassette (Compact Cassette) is the pocket magnetic tape that democratized the recording of music. It was developed by the team of engineer Lou Ottens at Philips — who wanted a tape medium that would fit in a jacket pocket — and it was presented to the public on August 28, 1963 at the Berlin Radio Show, together with its portable recorder, the Philips EL 3300.

Its master stroke was not only technical but commercial: Philips licensed the system free of charge to the other manufacturers, and the cassette became the world standard for home tape. For the first time anyone could record — from the radio, from a record, from a microphone — and take the music with them. That double condition, recordable and portable, is what made it indispensable for the culture of mobile sound.
