Abstract: The present invention relates to an airflow guidance structure in an optical storage carrier player. More particularly, the present invention relates to an airflow guidance structure in a CD-RW drive. The airflow guidance structure provides a path and cooperates with outlets disposed close to the end of the airflow guidance structure. Heat generated during the operation of the CD-RW drive is discharged from the outlets by using the airflow generated by the rotation of the disc.

Abstract: A frame body 11 disposed within a case body 2 is provided with a main-body portion 20 for rotating an optical disk 28 to thereby read recorded information therefrom. The frame body 11 is assembled with a cooling fan 13. The frame body 11 is provided with a duct part communicated with a suction side of the cooling fan 13. The frame body 11 is mounted with a circuit board 81 for closing a lower surface of the frame body 11 and covering the below of the main-body portion 20, to thereby define a machine room and an airflow path room within the case body 2. The circuit board 81 is formed with a through-hole 83. Fresh air is allowed to efficiently contact with electrical components to thereby cool them.

Abstract: A data storage system (30) includes multiple storage devices arranged in an array. A column in the array includes storage devices (12, 14, 16) mounted on a tray (22). The storage devices (12, 14, 16) and the tray (22) form an air channel (28) for efficient heat dissipation. The data storage system (30) may include multiple columns inserted in multiple slots of a chassis (35), thereby forming a memory board.

Abstract: A communication hole (55) is provided in a pickup base (51). A laser light source (61) is provided at an end of the communication hole (55). A grating (71) is provided at another end of the communication hole (55). The communication hole (55) is provided with a heat radiation path (81) which connects the inside of the communication hole (55) with the outside of the pickup base (51). Heat generated from the laser light source (61) is radiated from the heat radiation path (81).

Abstract: A laser light source (61) and a heat-radiating plate (71) are provided on a pickup base (51). The laser light source (61) irradiates a laser beam to an optical disk (41). The heat-radiating plate (71) has at least one part exposed outside the pickup base (51), having a predetermined distance between the heat-radiating plate (71) and the pickup base (51), and radiates heat generated by the laser light source (61). The plate (71) can radiate heat also from a surface opposing the pickup base (51) and can therefore have a high heat-radiating efficiency.
