• For rewriteable CD-RW, DVD-RW, DVD+RW, DVD-RAM, or BD-RE media, the laser is given to to melt a crystalline nail it alloy in the recording layer of the disc

• Depending on the bulk of power applied, the fabric may be allowed to melt back (change the phase back) into crystalline design or left in an amorphous form, enabling marks of varying reflectivity to be created.

Because unbefitting a constant transfer charge for the whole disc is Cassette to CD Recorder not so important in most contemporary CD uses, to keep the rotational speed of the disc safely ground-level while maximizing data rate, a pure CLV approach needed to be abandoned. Some drives elbow grease in partial CLV (PCLV) scheme, by switching from CLV to CAV only when a rotational brim is reached.
