(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 consists of an LSI chip to improve reliability. The high-
speed microprocessor unit (MPU) achieves a high-performance AT controller.
2.2 System Configuration
2.2.1 ATA interface
Figures 2.3 and 2.4 show the ATA interface system configuration. The drive has
a 44-pin PC AT interface connector and supports the PIO transfer at 16.6 MB/s
(ATA-3, Mode 4), the DMA transfer at 16.6 MB/s (ATA-3, Multiword mode 2).
