Summary on Grant Application Form
This is a collaborative proposal with the company Hewlett-Packard who are providing the capital equipment. The main objective is to increase the recording density of stationary-head tape systems by 30% through the application of two-dimensional sequence detection techniques. The next generation of tape-drive products will incorporate stationary heads with very high track densities. These will require coding/detection techniques to capitalise on the multiple-track structures. Two-dimensional codes promise a higher performance and are particularly applicable to these devices. Other applications are three-dimensional optical recording systems and communication channels.The aim is to enhance data-detection by capitalising on the two-dimensional aspect. In addition to imbuing data recorded/processed longitudinally with information which will subsequently aid detection, data recorded/processed laterally will also be similarly encoded. Each degree of coding will be inter-related such that recovery of data from one axis of encoding will be aided from information inherent in the other axis. Such a scheme will give improved performance compared with conventional, one-dimensional detection. A hybrid model of a multiple-channel system is established and used to compile a catalogue of performance for current two-dimensional codes. Novel, two-dimensional sequence detection methods will be devised and evaluated.
