Paperless recorder and method for storing data of same

The invention relates to a paperless recorder and a method for storing data of the same. The method comprises the following steps of: firstly, corresponding to the applied record channel, building an index for each record channel in an RAM index area after starting up, wherein data starting time, record points, starting positions of corresponding data blocks and record cycle information are stored in the index; then storing the data of all the record channels into an RAM data area; transferring the data stored in the RAM data area into corresponding data blocks in a memory data area according to the starting positions of the data blocks of corresponding index records when the RAM data area is full; continuously storing new data into the RAM data area; and transferring the data into a memory after the RAM data area is full until shutdown to complete data storage. The method effectively solves the problems that the conventional paperless recorder has the disadvantages of need of filling historical data for powe
