RK05 disk drive user's manual

This document is the user's manual for the Digital Equipment Corporation (DEC) RK05 Disk Drive, a self-contained, random-access data storage device. It is designed for small to medium-sized computer systems and data acquisition applications.

The RK05 uses high-density, single-disk 12- or 16-sector cartridges and features two movable read/write heads that operate at 1500 rpm, storing up to 25 million bits of data using a double-frequency, nonreturn-to-zero (NRZ) recording method. The drive is available in four models, supporting various 50/60 Hz AC power configurations (95-130 Vac and 190-260 Vac). Up to eight RK05 drives can be daisy-chained from a single controller bus.

The manual details the drive's major assemblies, including controls and indicators, the spindle and drive system, linear positioner, cartridge-handling system, logic assembly, air system, power supply, and read/write heads. It provides comprehensive instructions for unpacking, mechanical installation, and normal operating procedures for cartridge loading and unloading. Crucial sections are dedicated to cartridge handling practices and precautions, emphasizing proper storage, regular cleaning, temperature stabilization, and preventing contamination to ensure data integrity and prevent drive damage.

Furthermore, the document thoroughly describes the RK05's interface, outlining both input lines (e.g., drive selection, cylinder address, write data/gate, restore) and output lines (e.g., file ready, address accepted/invalid, seek status, write protect status, read data/clock, sector/index pulses, AC/DC low signals). An appendix is included for the RK05-TA Off-Line Tester, detailing its operational functions and connection procedures.
