Data recording apparatus, data recording method, and non-transitory computer readable medium

A data recording method executed by a computer, comprising the computer to perform operations including:

• obtaining multiple sets of measurement data obtained by measuring a measurement target;
• determining for every measurement data of the multiple sets of measurement data whether a data volume is capable of being irreversibly compressed;
• irreversibly compressing, in response to a result of the determining, the data volume for measurement data of which the data volume has been determined as capable of being irreversibly compressed;
• reversibly compressing multiple sets of measurement data including the measurement data of which the data volume has been irreversibly compressed;
• and
• recording the multiple sets of measurement data which have been irreversibly compressed and reversibly compressed.

A non-transitory computer readable medium having recorded thereon a data recording program that, when executed by a computer, causes the computer to function as:

• a data obtaining section for obtaining multiple sets of measurement data obtained by measuring a measurement target;
• a determining section for determining for every measurement data of the multiple sets of measurement data whether a data volume is capable of being irreversibly compressed;
• an irreversible data volume reducing section for irreversibly compressing, in response to a result of the determining, the data volume for measurement data of which the data volume has been determined as capable of being irreversibly compressed;
• a reversible data compressing section for reversibly compressing multiple sets of measurement data including the measurement data of which the data volume has been irreversibly compressed;
• and
• a data recording section for recording the multiple sets of measurement data which have been irreversibly compressed and reversibly compressed.
