Abstract

A method stores a plurality of sequentially ordered data samples in a plurality of sequential storage segments such that one of the plurality of sequentially ordered data samples is stored at one of the plurality of sequential storage segments which is non-sequential to another of the plurality of sequential storage segments in which an immediately preceding one of the plurality of sequentially ordered data samples is stored. Another one of the stored plurality of sequentially ordered data samples, other than a first ordered one of the plurality of sequentially ordered data samples, is overwritten with a further data sample, the further data sample being immediately sequential to a last ordered one of the plurality of sequentially ordered data samples.

Claims

1. A method for storing data, comprising the steps of:

storing a plurality of sequentially ordered data samples in a plurality of sequential storage segments such that one of the plurality of sequentially ordered data samples is stored at one of the plurality of sequential storage segments which is non-sequential to another of the plurality of sequential storage segments in which an immediately preceding one of the plurality of sequentially ordered data samples is stored; and

overwriting another one of the stored plurality of sequentially ordered data samples, other than a first ordered one of the plurality of sequentially ordered data samples, with a further data sample, the further data sample being immediately sequential to a last ordered one of the plurality of sequentially ordered data samples.

2. The method of claim 1, further comprising the step of:

storing another further data sample, the another further data sample sequentially following both the last ordered data sample and the further data sample, at another further one of the plurality of storage segments other than a storage segment storing one of the plurality of sequential data samples and a storage segment storing the further data sample.

3. The method of claim 1, wherein the plurality of sequential storage segments are one of sequentially addressed storage segments or sequentially located storage segments.
