Introduction to Compact Disc In Types of Compact Disc, Compact Disc, shortly called CD, has replaced tape media way back in the 1980s and it is used for storing Audio, Video, and Computer data files. Many Audio and video albums were released in CD format in the 1990- 2010 time period, and the CD was the standard media for software releases, upgrades, and License copies. The CD is the backup media for preserving important files for users, and all personal computers used have CD disk drives. The CD is a cheap, easy-to-carry, robust media, unlike Floppy, and it is highly user-friendly. It is a miniature version of yesteryear’s gramophone plate; the information is stored as pits and lands on spiral tracks on the surface of the CD. Red laser recognizes the pits and converts them into data. In this article, let’s study various types of CDs. Types of Compact Disc Compact Discs can be categorized on Operations Read-only, Recordable, Rewritable End-use Video, Audio, Photo, Graphics Quality of the content Super Audio, Super Video, Digital versatile disk DVD 1. CD-ROM ROM denotes Read-only memory. The content stored in these types of CDs can only be read but cannot be altered by anyone. Any standard Compact Disc player will be able to play this CD. This media was prominently used in the Pre-recorded music market initially. Subsequently, Computer software, Licenses, Data, and educational content are distributed thru these types of CDs. 650 MB of data can be stored in this media. 2. Recordable CD CD-R Contents can be written in this media by CD drive attached to a computer or an external CD drive. A fresh CD is coated with a dye that will undergo a change in color when light is passed on it. This dye is photosensitive in nature. CD writer, while writing data burning data, passes special laser rays on the dye and the change dye’s color. These CDs can be read through any normal CD player. While reading, the change in the color is sensed, and data is read, similar to reading data thru pits and lands in a normal CD. The physical dye layer has a shelf-life, and over the years, its characteristics may deteriorate, leading to errors. The life of a CD is dependent on the storage conditions and quality of the CD. Recording can be done only once on any given portion of the CD, and it cannot be rewritten or altered. Information can be added to the CD in the unburnt area. 3. Rewritable CD CD-RW This media uses metallic alloy as against dye in CD-R. During CD writing, the laser rays change the metallic alloy layer’s properties. Any change in the properties of the alloy, viz., crystalline or amorphous, can be tracked by its reflectivity, and this change is used while reading. Most CD readers can read the CDs burnt this way, bypassing lower intensity laser without altering the properties. Data in this CD can be erased, and new data can be stored any number of times. While rewriting, the metallic layer is initialized using laser rays by melting it, and the data is freshly stored. Writing takes more time than CD-R, the metallic layer deteriorates faster than dye, and the life of this media is lower when compared to CD-R. 4. Audio CD Sony and Philips came out with the format of this media in a document called Red Book, named after the color of the document’s cover. This format is officially called Compact Disc Digital Audio CD-DA. Additional text information like the name of the album, song, and singer are stored in an earmarked area of 5KB size in standard Audio CDs. These audio CDs can store graphical information also, but it requires an exclusive CD cum graphics player to display graphical data. The song’s lyrics are mainly stored in graphical format and displayed when the song is played. Sometimes the players are hooked onto a TV or PC monitor. The extended graphics version stores additional text/video information in sub-code channels, and there were few takers for this format. 5. Super Audio CD This format was again developed by Sony and Philips in 1999, providing a higher-fidelity audio format. These read-only optical discs filled the ears of music lovers with high-resolution quality. It had hybrid versions in which both a standard audio format and a super audio format were available. 6. CD-MIDI Used in storing music performance data and enabling audio synthesizing when it is played back in electronic instruments. 7. Video CD Video content is stored in a standard digital format on a CD. VCD standard, known as the white book standard, was developed in 1999 by Matsushita, JVC, Sony, and Philips. VCDs have a similar picture quality as that of VHS, and the quality of VCD does not deteriorate as fast as VHS upon its usage. This CD can be played on computers, VCD, and in some DVD players, and it has a resolution of 352 x 240. 8. Super Video CD It is a superior version with times the resolution of VCD. It is placed in between VCD and Digital video disc in terms of picture quality and technical features. It can hold long lengths of videos. 9. Photo CD Exclusively designed by Kodak to store high-quality scanned prints, slides, and images through encoding features. Any computers with specific software or photo CD players can play these CDs. 10. CD-i These Interactive discs store audio, video, and images, and a CD-I player is needed to play the contents in this multimedia disc. 11. DVD Digital Videodisc has 6 times the capacity of a normal CD and can store up to of content. DVD is used extensively in high-quality movie releases, and it is far superior then VCD and VHS. Interactive menus, commentaries, and deleted scenes are its unique features. It can store data on both sides top and bottom. It stores data in more than one layer aside. The size and the technology used are the same as that of normal CDs, but the multiple sides and multiple layers inside storage features give a clear edge to DVD. Conclusion With the availability of broadband internet and over-the-top products OTT products, audio or movie content are marketed over the internet as downloads. The software and license components are also downloaded over the internet. The usage of CDs has come down in the last decade, but CD is not extinct and is very much there.

Keuntungan dan kerugian Kelebihan: Kapasitas penyimpanan media ini lebih besar dibanding perangkat penyimpanan lainnya bahkan ke Petabyte dan kecepatan akses data cukup tinggi.Kekuranganmenggunakan CD : Mudah tergores dan menyebabkan data tidak bisa dibaca oleh komputer. Jadi simpan dengan baik CD-nya agar bagian dalamnya tidak tergores, sehingga lebih awet. CD bisa saja rusak jika disimpan dalam waktu lama, sehingga data didalamnya tidak bisa dibaca oleh komputer. Itulah keuntungan dan kekurangan dari Compact Disc. Selaintiga hardware utama tersebut, ada juga perangkat tambahan yang digunakan untuk mendukung kinerja komputer.
