Data recording method for storing first data and second data into a tape medium

摘要

Provided is a method for recording data to a tape medium in such a manner as to achieve the easy management of mutually related multiple data pieces. First data and second data continuously received as a file from a higher level apparatus are accumulated in multiple buffer segments in the form of multiple successive data sets. A data structure is determined for each of the accumulated data sets. Management information indicating a result of the determination is added to the data sets, and the data sets and the management information thereof are stored into the tape medium.

1. A data recording method for storing first data and second data into a tape medium by a processor device, the first data being main data and the second data being sub data related to the first data, the data recording method comprising the steps of:
accumulating the first data and the second data sequentially in a plurality of buffer segments in the form of one or more successive data sets in a predetermined size, the first and second data being continuously received as a file from a higher level apparatus; determining whether a data structure of each of the data sets accumulated in the buffer segments includes one or more of the main data and the sub data; adding management information to a corresponding one of the data sets, the management information indicating whether the data structure includes one or more of the main data and the sub data; and controlling storing, into the tape medium, the data sets accumulated in the buffer segments and the management information added to the data sets.
