2.2 System Configuration

(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 2.2 and 2.3 show the ATA interface system configuration. The drive has a 44pin PC AT interface connector and supports PIO mode 4 transfer at 16.6 MB/s, Multiword DMA mode 2 transfer at 16.6 MB/s and also U-DMA mode 5 (100 MB/s).
