The History Of The Compact Disc

They also increased the diameter of the disc from 115 mm to 120 mm.

The creation of the compact disc cannot be attributed to a single individual, but rather a combination of individuals and corporations. At some point in time, each had a hand in the development of the technology. It first started with James T. Russel, an American inventor, in 1966. At that time, he filed for two patents, one for synchronizing photographic records of digital information, and one for an analog to digital to optical photographic recording and playback system. These two patents formed the basis for the technology that would eventually lead to the compact disc.

He further refined his technology using a combination of digital recording, laser, and optical disc technology, and eventually succeeded in creating a system that could record and play back sounds without requiring physical contact between the components. In the 1970s, Philips and Sony licensed Russel's patents to develop their own prototype systems. In 1978, Philips decided that compact discs would be 115 mm in diameter and would be made from polycarbonate. They also decided on the type of laser that would be used by compact disc players. In mid-1978, Philips was the first to announce the technology to the public. They demonstrated the initial prototype in Japan and Europe in 1979.

Later in 1979, Philips and Sony formed a collaboration to further improve compact disc technology and decrease the timeline in which it could be released for sale to consumers. Between the two companies, it was decided that CDs would use a standard sampling rate of 44.1 kHz and use 16-bit audio. They also increased the diameter of the disc from 115 mm to 120 mm. These decisions allowed for a standard compact disc to contain up to 74 minutes of audio playback.

In 1980, the joint collaboration released the Red Book CD-DA, the first of a series that would eventually be known as the Rainbow Books. The Rainbow Books contain the technical specifications for all compact disc formats.

Sony released the first commercially-available CD player in 1982, the Sony CDP-101, followed soon by a model from Hitachi. At the time, it sold for $900 and was only available in Japan and parts of Europe. After gaining widespread popularity in these two markets, the technology was released in the United States in 1983.

How A CD Stores Data

Compact discs are made from polycarbonate plastic. A very thin layer of aluminum is applied to the polycarbonate surface, and then coated with a protective layer of lacquer. When completely assembled, a compact disc measures 1.2 mm thick and weighs roughly 16 grams. The polycarbonate surface of a CD has a series of molded spiral tracks. It is in these tracks that the data is stored.

a 1. This series of binary digits forms the data, which is played back as an audio track.

Grooves on the polycarbonate surface are known as pits. The areas in between the pits are referred to as lands. A standard compact disc contains somewhere between three and five million pits. As with many other forms of digital communication, binary code is used to as a method of storing and communicating data. When a compact disc is played, a read laser bounces beams of light off of the surface to detect the pits and lands. Each time the surface of a CD changes from a pit to a land, or a land to a pit, the system interprets it as a 0. If the surface has multiple lands or pits in a row, no change is detected by the system, in which case it is interpreted as a 1. This series of binary digits forms the data, which is played back as an audio track.

Burning a compact disc at home uses a similar concept to create data, but instead of creating actual pits and lands, a special dye is used to create reflective and non-reflective areas on the disc's surface. CD-Rs are created with a layer of translucent dye in between the aluminum coating and the polycarbonate surface. Before the dye is altered by a computer's write laser, a CD player's read laser can pass right through it and be reflected back. When burning a compact disc, the write laser generates heat, which turns the dye black in specific areas. Unlike the unburned areas of the dye, the burned areas are no longer reflective. Non-reflective areas of the CD surface are registered as a 0 and reflective areas are registered as a 1 by a CD player.

How A CD Player Works

Inside of every CD player is a semiconductor diode laser and a photoelectric cell. As you press play on the device, an electric motor spins the disc at speeds up to 500 RPM. Once the disc reaches the correct speed, the CD player turns on the diode laser and shoots it at the surface of the CD. The laser begins to scan the disc at the center and works its way outwards towards the edge. It is interesting to note that this is the opposite way an LP is read, where the turntable's needle starts at the edge and and works its way towards the center. As the laser works its way from the center of the disc outwards, the motor gradually slows down the disc's RPM.

The laser begins to scan the disc at the center and works its way outwards towards the edge.

When the laser hits the surface of the CD, it is reflected back off of the pits and lands and into the photoelectric cell, which detects the amount of light reflected. Pits scatter the light, which causes little to no light to be reflected back at the cell. Lands reflect the light directly back to the cell, without diffusing it in any manner.

When the photoelectric cell detects a land, it sends a burst of current to an electronic circuit somewhere in the device which registers as a 1. If no light is detected by the cell, there is no electric current sent and the circuit registers it as a 0. In this manner, the circuit slowly recreates the binary code that was originally used to store the data on the disc. Inside of the CD player there is a digital-to-analog converter circuit, often referred to as a DAC. This circuit decodes the binary digits and once again converts them back into a pattern of electric currents. It is these electric currents that the CD player's speakers transform into sounds.
