A compact disc is made from a 1.2 mm thick disc of almost pure polycarbonateplastic and weighs approximately 16 grams. A thin layer of aluminium (or, morerarely, gold, used for its longevity, such as in some limited-edition audiophile CDs) is applied to the surface to make it reflective, and is protected by a filmof lacquer. The lacquer is normally printed directly and not with an adhesivelabel. Common printing methods for compact discs are screen-printing and offset printing.
Por lo tanto sabemos que CD está hechos de plástico y una capa delgada de aluminio. Esto significa que podemos cortar y forma discos usando un cortador adecuado con un suficientemente alto RPM (revoluciones por minuto)
Disc shapes and diametersA Mini-CD is 8 centimeters in diameter.A Mini-CD is 8 centimeters in diameter.The digital data on a CD begins at the center of the disc and proceeds outwardsto the edge, which allows adaptation to the different size formats available. Standard CDs are available in two sizes. By far the most common is 120 mm in diameter, with a 74 or 80-minute audio capacity and a 650 or 700 MB data capacity. 80 mm discs ("Mini CDs") were originally designed for CD singles and can hold up to 21 minutes of music or 184 MB of data but never really became popular. Today nearly all singles are released on 120 mm CDs, which is calleda Maxi single. Por lo tanto, nos podemos cortar las partes exteriores de los discos que no hay datos escritos a ellos (siempre y cuando no hemos utilizado el espacio del disco entero)
Una manera fácil de asegurarse de que usted corte con seguridad es ver el lado brillante del disco y la zona que está más oscuro o sombra. Esto muestra el área del disco en el que se ha escrito datos. El resto del disco puede cortar lejos.
