I want to know the answer to the following question:
Who was the director of the Philips audio division in 1974?
All the background I'm provided with is that "In 1974, L. Ottens, director of the audio division of Philips, started a small group with the aim to develop an analog optical audio disc with a diameter of 20 cm and a sound quality superior to that of the vinyl record.". Is that enough to answer the question?
