laser

products are not considered to be hazardous. The

optical drive

contains

internally

a

Class

3B gallium-arsenide laser that

is

nominally

30 milliwatts at

830

nanometers. The

design

incorporates a combination of enclosures,

electronics,

and

redundant

interlocks such that there is no exposure

to

laser

radiation above a

Class
