The present invention achieves a configuration that prevents recording errors when data recording processing is performed on both the lands and the grooves of an optical disc. The present invention has a data processing unit that performs data recording processing control on both the lands and the grooves of an optical disc. When data is recorded onto a land or a groove, the data processing unit performs processing that detects a position at which the data recording states of both of the grooves or the lands that are adjacent to the land or the groove that is the data recording target coincide, or processing that makes the data recording states coincide. As processing that makes the data recording states of both of the grooves or the lands that are adjacent to the land or the groove that is the data recording target coincide, the data processing unit performs, for example, dummy data recording processing, skip processing, or the like.

The invention relates to an oil derrick stress measurement and data acquisition system based on a wireless sensor network, which comprises a vibrating string extensometer-detected marine oil derrick stress-strain subsystem, a marine oil derrick stress-strain field data transmission subsystem based on the wireless sensor network and a marine oil derrick capacity assessment subsystem based on a configuration technology and a Matlab computation program. In the system, an industrial computer is connected with a wireless sensor network gateway through an industrial concentrator, marine oil derrick stress-strain field data is converted into digital signals by wireless sensor network nodes, and then, the industrial computer reads data at each node in the wireless sensor network by using the Modbus TCP / IP communication protocol and an address distinguishing technology so as to realize the acquisition and transmission of the oil drilling derrick stress-strain field data. The system has the advantages of low cost and high stability, and is applicable to a derrick capacity detection and evaluation system in ocean severe environment.

The invention provides a terminal and a processing method after an access failure thereof. The method comprises the steps of establishing, by the terminal, an RRC (Radio Resource Control) connection with a first cell, wherein the first cell is a cell containing a PLMN (Public Land Mobile Network) selected by the terminal; and when the RRC connection establishment with the first cell is failed, logging, by the terminal, an access failure PLMN list, wherein the access failure PLMN list includes the PLMN selected by the terminal. According to the terminal and the processing method after the access failure thereof provided by the embodiment of the invention, the accuracy of a log can be implemented, and thus the log can be reported to a correct PLMN.
