RL11/01 Disk Subsystem Training Handout

This document serves as a technical training guide for the RL11/01 disk subsystem, which includes both the RL01 (5MB) and RL02 (10MB) disk drives. It details the subsystem architecture, including block diagrams of the controller and drive, explains the imbedded servo data format, and outlines subsystem commands such as Get Status, Seek, Read Data, Write Data, and Write Check. Additionally, the handout covers subsystem error codes, diagnostics (such as CVRLA, CZRLG, CZRLH, CZRLI, CZRLJ, CZRLK, and CZRLM), and includes sample bootstrap programs for memory testing.
