The following describes a procedure for measuring the temperature inside a
cartridge.
1) At the bottom of the cartridge, open a hole large enough for the thermocouple
to be inserted as shown in Figure 3.1.
2) Disassemble the cartridge.
3) Cut off part of the wall surrounding the optical disk (disk outer wall) as shown
in Figure 3.1.
At this point, cut off a section 5 to 10 mm in width from the disk outer wall.
4) Using an adhesive agent, affix the tip of the thermocouple to the opening of
the disk outer wall.
