Abstract
A method of merging and rewriting information contained in related data records recorded on first and second sections or files of storage media. (Typically, the 'sections' may be individual magnetic tapes.) In accordance with the invention there is provided the step of reading the data records recorded on the first section and rewriting the data records in alternating relationship with dummy data records on a third section of storage media. Related data records recorded on the second section and the third section are read and the information contained therein is merged. The merged information is then written onto the dummy data records on the third section of storage media to obtain merged data records therein. The procedure is repeated sequentially for each related pair of data records on the sections of storage media under consideration. In the preferred embodiment of the invention, inter-record gaps are provided between adjacent written records and the dummy data records are made of sufficient length to hold the merged information for a pair of related data records plus an additional safety gap length. In accordance with a further embodiment of the invention, the merging operation can be performed using only a single tape transport in situations where the data to be merged is obtained on a 'real time' basis, such as data obtained in real time at a well logging site.
