(5) Air circulation system
The disk enclosure (DE) is sealed to prevent dust and dirt from entering. The
disk enclosure features a closed loop air circulation system that relies on the
blower effect of the rotating disk. This system continuously circulates the air
through the circulation filter to maintain the cleanliness of the air within the disk
enclosure.
(6) Read/write circuit
The read/write circuit uses a LSI chip for the read/write preamplifier. It improves
data reliability by preventing errors caused by external noise.
(7) Controller circuit
The controller circuit supports Serial-ATA interface, and it realized a high
performance by integration into LSI.
