Japan-based Fujitsu Ltd has developed the world's smallest magneto- optical, (MO) disc drive for use in laptop and computer notebooks.

The drive, 140 by 101.6 mm and 17 min thick, weighs less than 300 grams, It has been developed for integration into portable computers, potentially replacing standard floppy disc drives. The researchers say that the new drive can store on industry-standard 8.9 cm optical disc tip to 230 megabytes of information - 160 times the capacity of the floppy disc. The MO discs are rewriteable and cannot be erased by accidental contact with a magnetic field.
