The invention provides in some aspects an improved method for transfer of digital media objects that includes storing a digital file on a first digital data device and migrating that digital file to a second digital data device by repeating a plurality of times the steps of: (i) transferring to a second digital data a respective piece of the digital file, (ii) storing that respective piece of the digital file on the second digital data device. The foregoing are effected so that no respective piece of the digital file is concurrently stored on the first and second digital data devices and/or, more generally, so that any same portion of the digital file that is concurrently stored on the first and second digital data devices comprises not more than an insubstantial amount of the digital data file. Methods and apparatus according to the invention can be used for the (re)sale, lending, streaming or other transfer of digital music, digital books and other digital media objects. |
