The advent of high-speed CD-ROM and DVD-ROM drives makes disc unbalance
an important issue. The forces generated increase with the square of the
rotational rate, so at high speeds, the forces are extreme. These forces
and resultant vibration can adversely affect disc performance and drive
life.
High-speed CD-ROM drives will reduce their read speed
if they have trouble reading the disc. One of the causes of speed reduction
is vibration caused by disc unbalance. Only a properly balanced disc will
provide the maximum throughput these drives are capable of.
Disc imbalance can be caused by thickness variation of
the substrate, lacquer coating, CD-R dye coating, or DVD bonding layer
as well as asymmetrical label design.
Applications:
Molding optimization
DVD bonding process control
Optimize performance of CD-ROM & DVD-ROM
Label art optimization
