The MD 122 dual 3 Mbyte flexible disk drive

The dual 3Mbyte flexible disk drive provides 6 Mbyte of formatted data storage in a compact package designed for in-built use. The two disks may be inserted or removed independently and share a common double ended spindle. A common actuator is used to position the four recording heads. High areal recording density is achieved using advanced technology recording heads and media in association with a microprocesor controlled environmentally compensated servo positioner. The drive incorporates an intelligent controller which provides sophisticated data handling functions and controls the drive in such a manner that the interface to the host is free of drive dependant parameters.
