Abstract
The interior of a casing or housing 8 for an optical disk drive apparatus is divided into a first space S1 where a optical head 3, an optical disk loading mechanism 7 and a means 15 for increasing the pressure to prevent the entrance of dust and dirt into the first space S1 from the outside are positioned and a second space S2 where an electrical equipment section 5, a power supply section 6 and a motor-driven fan 9 for cooling the second space S2 are positioned, whereby it is possible to effectively cool the electrical equipment section 5 and the power supply section 6 in the second space S2, as well as to prevent the optical head 3 in the first space S1 from being contaminated by dust and dirt, so that the operation of this optical disk drive apparatus can be effectively maintained in a stable condition.
