The short-lived iD Photo system — developed jointly by Sanyo, Olympus, and Hitachi Maxell — was announced to the public in July 1999, poised to enter the crowded market soon after. Sanyo and Olympus developed the drive mechanism, while Maxell was responsible for disk development. With a footprint of only 56.5 mm × 59.5 mm × 4.8 mm, the iD Photo disks were quite small, but boasted a storage capacity of 730 MB¹⁾²⁾.
