Apple computer has commenced work on revising its iPod mini, according to provisional reports.

Designs for the updates allegedly commenced over a week ago with the intention of officially unveiling the new models sometime next year, writes AppleInsider.

The new device will offer a 5GB hard disk with 1,250 music track capacity, therefore offering a 25 per cent memory increase on current iPods.

Leading technical design firm, Seagate Technologies, has been brought in by Apple to aid with the design of the new hard drive, adding to current contributions from Toshiba and Hitachi.

The previous iPod mini model was released in January this year but due to poor planning, was unable to meet consumer demand until midway through the year.
