3.1.2 Temperature requirements and measuring method

Table 3.1 shows the temperature requirement at each measurement point shown in
Figure 3.1.

* Following procedure is for temperature measurement of inside cartridge.
1) Make a hole for the thermocouple as shown in Figure 3.1.
2) Disassemble the cartridge disk.
3) Cut off a part of the partition wall for the optical media as shown in Figure
3.1. (Cut off width: 5 to 10 mm)
4) Fix the tip of the thermocouple to the cut portion of partition wall with an
adhesive agent.
5) Pass the thermocouple through the hole at the cartridge case and assemble the
cartridge disk. When there is a gap between the hole and the thermocouple,
fill the gap with the adhesive agent.
Note:
The surface of the cartridge shown in Figure 3.1 has been cut away to make
the elements inside the case clearly visible. In reality the surface is not cut
away.
If the external environment temperature is higher than the specified value, the
device will automatically take an interval to respond to command, and then
take protective action to respond to the temperature increase.

3.1.3 Air flow

It is recommended that this optical disk drive be installed in a fanless cabinet.
However, if the power supply is incorporated into the same cabinet, it is necessary
that it satisfy the "Temperature Conditions" in 3.1.2 and that the air flow rate
being drawn in by the device) at the cartridge loading slot be 0.3 m/s or lower.
Furthermore, if there is a system fan in a system where this drive is being installed,
the same conditions must be met.
