<p>PROBLEM TO BE SOLVED: To avoid a bottleneck of a practical maximum transfer capacity of a local bus by communicating information by using the other PC card that is connected to an information processor and a 2nd information communicating means. SOLUTION: An SCS12 controller 205 reads data from a file in DVD-ROM 203 and sends the data to a card bus controller 204. Here, when it is instructed to communicate by using an optical communication transmission path 214 between PC cards 201 and 202 without using a card bus 13 according to an instruction group that is sent from a host CPU, the controller 204 sends the data that is received from the DVD-ROM 203 to a transmission controller 206. The controller 206 performs error correction coding of the data from the DVD-ROM 203, drives an optical transmission module 207 based on the data and sends information to the other PC card 202.</p> |
