A PROPOSAL TO STUDY INFORMATION STORAGE RROBLEMS

信息论中一个相对较新的研究领域涉及存储系统的编码和信息容量概念。随着新的高密度记录介质的发展，例如光学和磁光技术，需要用于各种存储系统的数学模型，以便可以获得最大的效率和可靠性。该项目涉及这些模型的开发以及有效存储的良好代码的开发。研究了代码的实现和复杂性方面，并确定了各种模型的信息存储容量。这些模型包括“写一次存储器”(WOM)、“写单向存储器”(WUM)及其统一和概括--“写高效存储器”(WEM)。

A relatively new area of research in information theory concerns coding and information capacity concepts for storage systems. As new high.density recording media are developed ; e.g., optical and magneto.optical techniques, there is need for mathematical models for a variety of storage systems in order that maximum efficiency and reliability can be attained. This project is concerned with the development of these models as well as the development of good codes for efficient storage. The implementation and complexity aspects of the codes are examined and the information storage capacities of the various models are determined. The models include "Write.once memories" (WOM), "Write.unidirectional memories" (WUM), and their unification and generalization, "Write.efficient memories" (WEM).
