Compact Disc Technology: In-Depth Technical Analysis
Linear and Angular Speed
The linear speed of the disc must be very precise. To start reading in the center of the disk, the angular speed is 500 rpm. As the beam moves outside the disc, the shaft speed decreases to 200 rpm, as the linear speed remains constant.
The Pickup
Compact disc reading requires optoelectronic elements that enable the broadcasting of the light source, the fitness, and focus that focus on the pit and reflected light detection, which allows reading and correction of errors. It

Iron
Iron has high thermal and electrical conductivity and is a special magnetic element. It exhibits great malleability and ductility, with a fusion temperature of 1537ºC. However, it is vulnerable to oxidation.
Aluminum
Aluminum is soft and has low mechanical strength. Its fusion temperature is relatively low, between 650ºC and 750ºC. Aluminum is frequently used in light alloys to achieve the minimum weight possible with acceptable mechanical strength. It is combined with magnesium and titanium

Generators
Generators are operators capable of transforming various forms of energy into the electrical energy required to operate different types of automatic and electronic devices.
Batteries
A battery supplies electrical energy through the conversion of chemical energy stored in a substance that leads to the interior.
Ohmic Resistance
Ohmic resistances are electronic components that offer a certain opposition to the flow of electrical current, producing a “fall” of tension between its extremes, called
