In 2000, one of the biggest news stories was the rise of Napster and similar file-sharing programs. With these programs, you could get an MP3 version of just about any song you want without shelling out a dime. The record companies were fairly upset over this turn of events, and understandably so: They weren't making any money off the distribution of their product to millions of people.
An external writable CD drive, also called a CD burner: With this type of drive, you can take music or data files from your computer and make your own CDs.
But there was money to be made on the "Napster revolution," as electronics manufacturers and retailers soon discovered. In 1999, 2000 and early 2001, sales of CD burners and blank CD-Recordable discs skyrocketed. Suddenly it was feasible for the average person to gather songs and make their own CDs, and music-mix makers everywhere wanted to get their hands on the means of production. Today, writable CD drives (CD burners) are standard equipment in new PCs, and more and more audio enthusiasts are adding separate CD burners to their stereo systems. In less than five years, CDs have eclipsed cassette tapes as the mix medium of choice.
In this edition of HowStuffWorks, you'll find out how CD burners encode songs and other information onto blank discs. We'll also look at CD re-writable technology, see how the data files are put together and find out how you can make your own music mixes with a CD burner.
CD Basics
A CD has a long, spiraled data track. If you were to unwind this track, it would extend out 3.5 miles (5 km).
If you've read How CDs Work, you understand the basic idea of CD technology. CDs store music and other files in digital form -- that is, the information on the disc is represented by a series of 1s and 0s (see How Analog and Digital Recording Works for more information). In conventional CDs, these 1s and 0s are represented by millions of tiny bumps and flat areas on the disc's reflective surface. The bumps and flats are arranged in a continuous track that measures about 0.5 microns (millionths of a meter) across and 3.5 miles (5 km) long.
To read this information, the CD player passes a laser beam over the track.
12. DVDs are digital versatile disc, optical discs used to externally store data. DVDs have higher recording and retrieving speeds, are better suited for backing up information, and have higher capacity per device than
The author had an interesting first hand encounter with a homeless person. He stated that the incident did nothing to spark any concern for the homeless, however it did make him notice and avoid the street beggars. The author assumed that since nearly everyone else avoided them, the answer was simply to just keep walking and ignore them. One of the facts that was stated in the story was that the 1980’s saw a brief period of homelessness. The author demonstrated that he saw what the rest of society chose to ignore even if it was right in front of their face the whole
How a record player works is quite simple. A motor is somehow connected to a solid disc so that the disc is rotated at a constant speed. On top of the rotating disc (platter), The record is placed on top, with a slip mat in between. The slip mat can serve two functions. In the past to hold the record in place so that it would not rotate independently of the platter. Now, however, the slip mat serves a much different function. Instead of holding the record in place, the slip mat is now used to reduce the friction between the spinning platter and the record. This way a DJ can scratch (manually move the record, usually at high speeds) the record while the platter continues to spin underneath. Once the record is rotating, a stylus glides along the grooves and picks up the vibrations, these are then converted into audible sound.
Sound quality is an essential part of any sound machine. What good would an audio machine do if you can’t understand the music or the person speaking? The early recordings of the phonograph were poor. The quality was bad, the recordings were brief, and it could only be used two to three times. It shows how the phonograph doesn’t hold up. These new CDs blow
The Use of Electronic Technology in 20th and 21st Century Music In this essay, I have examined the use of electronic technology within 20th and 21st Century music. This has involved analysis of the development and continuing refinement of the computer in today’s music industry, as well as the theory of the synthesiser and the various pioneers of electronic technology, including Dr. Robert Moog and Les Paul. Also within the essay, I have discussed the increasing use of computers in the recording studio. The computer has become an indispensable tool in ensuring that both recording and playback sound quality is kept at the maximum possible level. Many positive ideas have come from the continued onslaught of computerisation.
fed into a DTS decoder, of which several DTS equipped consumer receivers and processors exist, you get a high quality 5.1 music format. Many people don't realize that there is a viable 5.1 music format available today with a catalog of a couple hundred popular CDs available.
One needs to recognize that homelessness impact’s a person’s ability to enjoy basic needs and freedoms. It has important consequences for the way that society perceives and treats people. One of the biggest effects of homelessness is the breakdown of a community itself. Many people do not
I’d like to start things out by taking a survey. How many of you remember having a CD player in your house fifteen years ago? Not very many of you, I see. Of course, we all have CD players now. It took a little over a decade and some major price drops, but eventually we all threw out our old vinyl and cassettes and opted for the excellent sound quality and convenience of CDs.
For many homeless people, it is some strange turn of events causes them to lose everything. Then after months of rejection, they begin drinking and doing drugs. Eventually, the emptiness sets in so they begin talking to themselves. They don’t have anywhere to shower or get the mail. Eventually, they lose touch with society.
Edgar Allan Poe’s “The Raven” is a dark reflection on lost love, death and loss of hope. This poem dramatizes the emotions of the poet, who has lost his beloved, and unsuccessfully tries to distract himself from sadness, through studying books. However, books are little help and a single visitor, a Raven, disturbs his solitude. Through the poem Poe uses symbolism, imagery and tone to enforce his theme of sadness and loss. Also, with the use of assonance, alliteration, rhyme and repetition, the poem achieves a melodic level that almost feels like singing when read out loud!
Walking down the streets of large cities it is common to see men, women, and sometimes even whole families laying beside buildings. Some people may ignore them and keep walking, some feel frightened, and some see the homeless as a human being and treat them like one. These people tend to be dirty, smelly, or they have a sad look that has overtaken their faces because of their struggle to survive. The people sleeping outside of buildings are homeless. Being homeless means not having anywhere to call home, although it also can mean living in a place that was never intended to house humans, such as a bus stop or a highway underpass. It is tempting to wedge the homeless together under a single label but there are an abundance of contrasting causes

In 1972 Philips announced a technique to store data on an optical disc. First in 1981 Philips and Sony proposed the Compact Disc Digital Audio standard (CD-DA) which was coded in the so-called Red Book [Philips and Sony Corporation, 1991]. The development of this technique revolutionized the audio world by introducing truly digital technology for the first time. It was in the year 1982 that Philips and Sony launched the first players and discs on the market. The CD became the music carrier of choice by 1991, when sales exceeded those of audio-cassettes.
In the past two decades, a form of physical music has gone from almost obsolete to a growing industry that appears to be going nowhere but up, in sales and possibilities. Before the introduction of the Compact Disk by Sony and Phillips in 1982, Long Play albums, or LPs, were a booming industry in the music world (Liversidge). However, the convenience, portability, and durability of CDs lured music fans away from vinyl very quickly. But alas, as time goes on and types of music consumption evolve, more types of physical music continue to decline in sales. After the introduction of Napster in 1999, Pandora in 2004, and Spotify in 2011, CDs have become a thing of the past (Evren).
