In a multichannel seismic system, channel-sequential seismic data samples gathered during a first recording cycle are demultiplexed to sample-sequential format in a core memory. The core memory is divided into pages each of which is addressable in two dimensions by rows and columns as a rectangular matrix. The channel-sequential data samples are serially loaded into the respective pages in channel-sequential order by columns. At the end of the first recording cycle, the data are extracted from the respective pages by rows in sample-sequential order. As the data samples from the first recording cycle are being extracted by rows, data samples from a second recording cycle are loaded serially by rows into the respective pages that were vacated by the extracted data samples of the first recording cycle. Data samples from the second recording cycle are then extracted by columns in sample-sequential order and a third set of data samples is loaded serially in vacated elements of the columns, thereafter to be extracted by rows. The process is repeated for the data samples from additional recording cycles.
