Patent ID: 8310490

Claim:
A computer memory system comprising: a media module configured to store electronic data; a host computer comprising: a docking station configured to accommodate the media module in removable fashion; an interface through which electronic signals representing the electronic data are transmitted between the host computer and the media module; an optical indicator; a host processor configured to control a read/write operation over the interface between the host computer and the media module and to activate the optical indicator whereby the optical indicator provides a first optical signal depicting transmission of electronic signals over the interface in the read/write operation, the host processor further being configured to drive the optical indicator whereby the optical indicator provides a second optical signal modulated to represent media module management information, the first optical signal and the second optical signal not being transmitted over the interface; a display unit comprising: an optical receiver configured to receive the second optical signal; an output display device configured to provide a visible representation of the media module management information; a display unit processor configured to interpret the second optical signal and to display the media module management information derived there from on the output display device; wherein the display unit further comprises a memory, and wherein the display unit processor is further configured to store the media module management information derived from the second optical signal in the memory and upon request to drive the output display device with the media module management information obtained from the memory.
