Dutch engineer Lou Ottens isn’t a household name – but he should be. Reel-to-reel tape recorders were fast becoming commodity items by the early-1960s and while the transistor had been responsible for new portable designs, the tape system itself still required the dexterity of a surgeon, as users navigated lacing the tape around pinch-rollers, guides and heads. Efforts to encase the tape reels into a simple snap-load cartridge system weren’t new. However, it would eventually take two technology giants playing ‘hardball’ to get Ottens’ new technology its place in history.

Work on an audio-cassette began back in the 1950s, with the huge Radio Corporation of America (RCA) releasing the ‘Sound Tape Cartridge’ in 1958. However, despite its clear convenience over reel-to-reel tape, the format disappeared six years later. Suggested reasons for its failure vary, but RCA’s slowness to release pre-recorded music tapes and domestic players is often cited.
Meanwhile in Europe, German maker Grundig was the ‘market goliath’ in tape recorders and in 1961, reportedly partnered with Dutch giant Philips to create an audio-cassette. The problem for Grundig was Philips also had its Belgian team (including engineer Lou Ottens) working on an alternate design. Ottens’ ‘Pocket Recorder’ design eventually won out, leaving Grundig’s joint-effort out in the cold. Despite Philips’ offer to Grundig to join its ‘Pocket Recorder’ group, Grundig was
