Task 3:
Each instrument is recorded using a microphone. The sound are fed to a mixing
desk. The recording level are controlled and the EQ is adjusted by the sound engineer.
The output is recorded on a multitrack. The sounds from the multitrack are mastered
back through the mixer. The tape is remixed until the musicians are happy with the
sound. Special effects can be added on the mixing desk. The remixed tape is mastered
down to produce a master tape. This can be used to produce copies in many different
formats.

Task 6:
Fistly, a blank perspex disc is grinded and poslished to optical flatness. Next, it is
washed and spin-dried. It is then coated with a thin layer of photoresist and cured in an
oven. After that, as the disc is revolved, a laser beam is used to mark audio information
pattern on its surface. This process is known as ‘cutting’ disc. The photoresist is then
developed and etched to produce pits in the disc’s surface. These pits represent the
digital audio pattern. The disc is then given a thin silver coat to make it electrically
conductive. Next, the electroplanting is used to make a series of positive and negative
copies of the master disc. The final negative copy is used to make a large number of
indentical CDs. The surface of CD containing the pits marks is then coated with a 10


mm layer of aluminium, followed by a protective layer of plastic. Afterpunching the
centre hole,a label is applied and the CD is packaged.
