This document is the RK06/RK07 Disk Drive Service Manual, published by Digital Equipment Corporation in 1978. It serves as a comprehensive guide primarily for Field Service personnel for the maintenance, troubleshooting, installation, and adjustment of the RK06 and RK07 disk drives.

The manual details:

• Maintenance Philosophy: Emphasizes troubleshooting down to and replacing defective Field Replaceable Units (FRUs), with provisions for component-level repair.
• Tools and Equipment: Lists specialized tools and diagnostic programs required for servicing.
• Preventive Maintenance: Outlines scheduled inspection, cleaning, and testing tasks (e.g., head alignment, spindle ground checks, diagnostic performance tests).
• Subsystem Removal and Replacement: Provides extensive, step-by-step procedures for the removal and reinstallation of a wide array of disk drive components, organized by areas like the front bezel, rear cover, lid assembly, and baseplate.
• Adjustment Procedures: Offers detailed instructions for critical adjustments and alignments, including the latch assembly, speed sensor, belt tension, read/write and servo head alignment, home lock solenoid, tachometer magnet, glass shutter, velocity transducer, carriage roll, power supply, and VCO.
