Who Invented the Compact Disc?

The compact disc was the product of a collaboration between two major electronics companies—Sony and Philips. The idea of an optical disc for data storage was not entirely new, but these companies were instrumental in turning the concept into reality. The project was spearheaded by Philips engineer Kees Schouhamer Immink and Sony’s Norio Ohga. Both played pivotal roles in refining the technology and setting the industry standards that would define the CD as we know it today.

Their combined efforts led to the creation of the Red Book standard in 1980, which outlined specifications for audio CDs. This standard remains the basis for all compact discs even today. Without their vision and technical expertise, the CD might never have achieved the global success it did.

When Was CD Invented? A Timeline of Development

The journey to the invention of the compact disc is a fascinating tale of innovation and perseverance. Here’s a detailed timeline of the critical milestones that led to the creation of the CD:

• 1960s: The concept of optical data storage begins to take shape, with researchers exploring ways to use lasers for reading and writing data.
• 1970: James T. Russell, an American inventor, designs the first digital-to-optical recording and playback system, laying the groundwork for future optical discs.
• 1979: Philips and Sony announce their collaboration to develop a digital audio disc. This partnership would eventually lead to the invention of the CD.
• 1980: The Red Book standard is published, detailing the technical specifications for audio CDs, including a 120mm diameter and 74-minute playback capacity.
• 1982: The first commercial compact disc, an album by Billy Joel titled "52nd Street," is released in Japan. This marks the official debut of the CD.

By the mid-1980s, CDs had become a global phenomenon, quickly replacing vinyl records and cassette tapes as the preferred medium for music enthusiasts.

How Does a Compact Disc Work?

The compact disc operates on a simple yet ingenious principle: the use of lasers to read and write data. Here’s a breakdown of how it works:

1. Structure: A CD consists of three layers—a polycarbonate plastic base, a reflective aluminum layer, and a protective lacquer coating.
2. Data Encoding: Digital data is encoded as tiny pits and lands on the aluminum layer. These pits and lands represent binary code, which is the language of computers.
3. Laser Reading: A laser beam in the CD player scans the surface of the disc, interpreting the pits and lands as digital signals.
4. Conversion: The digital signals are then converted into analog signals, which are amplified and played as audio or displayed as data.

This optical technology allows CDs to store large amounts of data with high fidelity and reliability, making them a versatile medium for various applications.
