A battery-operated, hand-held disc drive for an optical data storage disc
contains a radio transceiver. Data read from the disc, for example a game
or movie, are delivered to the transceiver and transmitted, preferably
using a WiFi protocol, to a host device, such as a smartphone, PDA,
ultra-light tablet or notebook computer, or digital TV. Preferably, the
compression factor of the data on the disc and the transfer rate of the
data from the disc drive to the host device are set such that that disc
drive has a low duty cycle, thereby conserving battery power while
providing the user with an extended usage period. To provide a
high-quality experience, the data on the disc are compressed using a
highly efficient data compression algorithm such as MPEG-4.
