Study this diagram of the stagesin the manufacture of CDs.With the help of thediagram,discuss how CDs are made.2 Eachof you has a set of short texts describing some ofthe stages.Try to match each ofyour texts to one ofthestagesin the diagram. Be careful - some of the stagesarenot shown in the diagram.LASER BEAMRECORDINGI Discussyour information with your partner and agreeon the correctorder for all ofthe texts.StudentAStudent BGo to p.111.From the Father,multÍplepositive image metalMothers are made by electroforming.Each Motherin turn produces a negative image Son which is alsoknown as a stamper.The glassmaster disc is placedin a chemicalbath.The resist coating is not affectedbut where the laserhas removed the resist,the chemical etchestiny pitsinto the surface ofthe glass.Each disc is finished by applying a thin coating ofaluminium to form a reflectivelayer.The disc isthen coveredwith a protectivecoating of clearplastic,inspected,and labelled.METAL-METALMASTER(rarurn)FATHER(-)-Work in groups of three.Make a list of at least nine foodand drink products which, Iike bread,aremanufactured on a large scale.Chooseone from your list and try to explain to theothersin your group how it is made using your ownknowledge of the process.Now combine information as a group to try to make abetterexplanation.
