The '''Acorn double density 3 1/2" disk''' was used with Acorn computers, a line of computers from the UK in the 1970s through 1990s, which included the popular BBC microcomputer, and eventually led to [[RISC OS]]. It succeeded the [[Acorn double density 5 1/4" disk]], and was succeeded by the [[Acorn high density 3 1/2" disk]].

The disks were double sided, with 80 tracks per side and variants having 16 sectors of 256 bytes, and 5 sectors of 1024 bytes, for a total capacity of 640 or 800 kilobytes respectively. [[MFM encoding]] was used.

The [[ADFS]] (Advanced Disc Filing System) was used as the file system, and [[BBC BASIC tokenized file]]s were among the file types stored.
