L\u2019objectiu principal del treball era determinar algunes de les caracter\u00edstiques dels CDs i DVDs. Entre aquestes es trobaven les dimensions d\u2019un land i d\u2019un pit i la capacitat d\u2019emmagatzematge de cadascun. Per fer-ho, em valdr\u00e9 de dades gen\u00e8riques dels discs (\u03bb de funcionament, ampl\u00e0ria i llargada m\u00ednima pit\/land) i del resultats dels experiments.
L\u2019experiment era molt simple, consistia en fer incidir llum d\u2019un punter l\u00e0ser en un CD o DVD i determinar l\u2019angle format pels diferents rajos refractats. Gr\u00e0cies a aquest, es troba la separaci\u00f3 entre pistes, que,
combinada amb algunes dades gen\u00e8riques dels discs, en permet obtenir la capacitat d\u2019emmagatzematge dels dispositius.
Els resultats mostren una separaci\u00f3 de 1.4 \u03bcm entre les pistes del CD, cosa que el dota d\u2019una mem\u00f2ria de 751 Mb. En canvi, les pistes d\u2019un DVD estan separades per 0.69 \u03bcm, tenint aix\u00ed una capacitat total de 2.9 Gb.
Excepte aquest \u00faltim valor, la resta s\u00f3n for\u00e7a correctes, tenint en compte com es va realitzar la pr\u00e0ctica.<\/p>\n
