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.

3.1.3 Temperature rise

Table 3.2 Temperatures at measuring points (Reference)

[Ambient temperature of the optical disk drive: 45°C]			(°C)
	Measurement point	Random seek		Criteria
	Inside cartridge	54.0°C		55°C
	IC (controller) surface	70.5°C		95°C
	IC (read amp.) surface	72.4°C		85°C
	Thermal sensor	54.2°C		––
	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.

3.1.4Air cleanliness

The air cleanliness in the device environment is expressed by the number of dust particles per unit area. Fujitsu recommends using the optical disk drive in the environment of class 5 million or less particle level. (Class 5 million: This means there are 5 million dust particles of 0.5 ?m diameter or larger per cubic foot. This is equivalent to 0.15 mg/m3.)
