Method of operating a disc drive and a host device

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 t...

description 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.
