Multi-track run-length-limited (d,k) modulation codes were recently introduced as a method to increase storage densities in magnetic and optical recording systems. These codes are a generalization of the usual run-length-limited (d,k) codes and provide for increased storage density by relaxing the k-constraint and encoding multiple tracks in parallel. This dissertation focuses on methods of constructing such codes. Two methods are presented. The first uses state-splitting to construct multi-track (d,k) trellis codes. An example is presented in which a (1,3) trellis code is constructed having a code rate of R = 2/3. The second method results in the construction of multi-track (d,k) block codes which are implemented via an enumeration scheme based on the trellis description of the (d,k) constraints. This implementation results in memory requirements which increase only linearly with block length as opposed to the exponential increases arising from look-up table implementations. Additionally, a new class of multi-track codes referred to as redundant multi-track (d,k) codes, is introduced. These redundant codes, unlike the original multi-track (d,k) codes which are completely intolerant of faulty tracks, allow for r faulty tracks while maintaining synchronization.

This thesis is concerned with interfacing a magnetic stripe reader with an AT&T PC 6300 consisting of a 20 MB hard disk and with collecting laboratory usage statistics. Laboratory usage statistics includes the name and social security number of the student,along with other necessary details. This system replaces all manual modes of entering data, checks for typographical errors, renames the file containing a particular day's data to a file that has the current day's date as its new filename, and keeps track of the number of students for a particular day. This procedure will ensure security of laboratory equipment and can be modified for each computer laboratory on campus. The program results indicate an acceleration of data entry, favorable student response, and an increase in the accuracy of the data recorded. / Department of Computer Science
