“In 1953, Sony’s co-founders recruited Ohga while he was still studying at the Tokyo National University of Fine Arts and Music and hoping to pursue a career as an opera singer. They sensed his knowledge of sound and electrical engineering would benefit the firm.He was an executive by his 30s – a rarity in a Japanese company – becoming the president of CBS Sony Records (now Sony Music Entertainment) in 1970s.
From the start, he recognised the potential of the compact disc, and personally drove Sony’s initiatives to introduce the format.
During the development of the CD, it was Ohga who pushed for a disc that was 12cm (4.8in) in diameter, because it provided sufficient capacity at 75 minutes to store all of Beethoven’s Ninth Symphony.”
