Abstract
To simplify a cooling design of slim-type BD optical pickup, we created a simple analysis model based on the thermal network method. This model can simulate a various situations by changing the thermal resistances. In our case, the separation of the heat dissipation path between the BD-LD and the step motor via the bottom cover was simulated. As a result, it is found that the BD-LD and the step motor can be simultaneously operated at the applicable temperature. Moreover, we measured the temperature of working sample and the results showed good agreement with the results calculated by our model.
