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. 

5)  Pass the thermocouple through the hole in the cartridge and reassemble the 

cartridge.   

Using an adhesive agent, etc., fill any gap between the hole and the 
thermocouple. 

Note: 

The surface of the cartridge shown in Figure 3.1 has been cut away to 
illustrate the elements inside the cartridge.  Do not actually cut away the 
surface. 

 

If the external environment temperature rises above the specified value, 
the drive will take protective action to deal with the temperature increase 
by automatically placing an interval between commands before 
responding to a command.

Notes: 

1.  The above data was taken in a constant temperature chamber in which the 

temperature around the optical disk drive was kept at 45°C.  The data was not 
taken with the drive installed in a box in which the drive is actually used. 

2.  Note that, when installed in a box, the ambient temperature around the drive 

will differ depending on the air circulation conditions of the box, and the 
temperature increase inside the cartridge will differ accordingly.
