It is a rewritable magneto-optical disk cartridge based on the AS-MO (Advanced Storage-Magneto Optical) standards.
It boasts a 730MB capacity, giving it the ability to store more data than most other storage devices as used in digital cameras of its time period, by about 20 times. It could store around 1,800 2-megapixel images (400KB apiece) or 20 minutes of 30 fps 320 × 240 video footage (4.8Mps).
The disk also had a read/write speed of 10 to 50 Mb/sec, which was very fast for its time. The data contained on the disk could be overwritten over a million times, and it had an advertised life expectancy of 100 years.
The solid cartridge body measures 59mm × 56mm × 4.8mm (equivalent to 2.3" × 2.2" × 1/5"), making it very compact. It also had a secure seal.
The disk itself has a 0.6µm track pitch and 0.235µm shortest mark length (and shortest bit length), and is 0.6mm thick.
It was introduced in 2000 alongside the iDShot IDC-1000Z digital camera, for which it was designed. While other companies, such as Ricoh, Minolta, Nikon, and Olympus showed interest in the iD Photo disk technology, with the latter having planned to produce a camera, only Sanyo had ever made products that use the format.
However, due to the poor sales figures of the iDShot IDC-1000Z and the disks, the iD Photo format was discontinued in 2002.
