In accordance with an embodiment, a data processing system includes a processor, a memory, and an interface port configured to be coupled to a hardware network interface device. The indexable insert is attached, when used, to a shank or holder having fluid inlet and outlet passages. A data-format identifying section 86 determines whether data recorded on the optical disk is a photo movie based on the read-out ARI_DATA. As a result, the fluid-resin embedding section is thoroughly filled up with the resin without leaving any air, and the reliable PWB is thus obtainable. The wireless network derives an indication of ME speed and transmits the speed indication to the ME using a point-to-point message.
