ABSTRACT:
A method for detection of a sequential data stream which can be performed without host computer intervention is disclosed featuring examination of a data record and channel program during read operations for signals indicative that the data is not part of a sequential data stream, for example, embedded seek instructions. If a particular sought for record does not contain such indications, the successive record or records may then be staged to a faster access memory device such as a solid-state cache. The invention is described in a plug-compatible, software-transparent configuration.
