Optical disk drives

An optical disk drive uses laser technology to write data to and read data from an optical disk. The optical disk drives use removable media. The following are the different types of optical disk drives:

• Library-resident (in 3995 libraries)
• Operator-accessible (3995)
• Multifunction (library resident or operator-accessible in all 3995 models except 3995-131 and 3995-132)
