Do not attempt to operate the drivewhile it is disassembled. Do not attempt to open the covers of the drive as itis not serviceable and is to be replaced as a unit.Class 1 laser products are not considered to be hazardous. The optical drive con-tains internally a Class 3B gallium-arsenide laser that is nominally 30 milliwatts at830 nanometers. The design incorporates a combination of enclosures, electronics,and redundant interlocks such that there is no exposure to laser radiation above aClass 1 level during normal operation, user maintenance, or servicing conditions.Preface xiii
