scope:

This part of ISO/IEC 9318 describes the Logical Level 3 (generic level) Interface for magnetic and optical disk drives. The physical, electrical and configuration characteristics and the transmission protocol of this Interface are in accordance with ISO/IEC 9318-1. The interface is capable of handling data rates from 0 to at least 10 Moctets/s, depending on driver and receiver classes. The purpose of this part of ISO/IEC 9318 is to facilitate the development and utilization of an intelligent interface which permits the interconnection of multiple peripheral types such as disk, tape, communications, to a controller.
