- The Sony CDP-101, released on October 1, 1982, was the first compact disc player sold to the public, marking the beginning of the CD era.
- It introduced digital music playback in homes, replacing analog formats like vinyl records and cassette tapes with optical disc technology.
- The development of the CDP-101 was a result of collaboration between Sony and Philips, combining Sony's digital audio expertise with Philips' optical disc technology.
- Key engineers like Toshitada Doi (Sony) and Kees Schouhamer Immink (Philips) played crucial roles in developing the CD's technical standards, including the 16-bit resolution and 44.1 kHz sampling rate.
- The CD format was designed to hold 74 minutes of music to accommodate Beethoven’s Ninth Symphony, a requirement set by Sony chairman Norio Ohga.
- The CDP-101 used a semiconductor laser to read digital data from discs, employing error-correction systems like CIRC to ensure reliable playback.
- Early CD players, including the CDP-101, faced criticism for sound quality issues like phase shifts and 'brick-wall' filtering, leading to debates between analog and digital audio enthusiasts.
- The CDP-101 launched with a price of 168,000 yen (around $730 USD), positioning it as a high-end product, and came with an initial catalog of about 50 CD titles.
- Sony later introduced the portable Discman D-50 in 1984, making CDs more accessible and popularizing the format globally.
- Despite early challenges, CDs quickly dominated the music industry, replacing vinyl and cassettes within a decade.
