    The development of IBM thin-film inductive recording heads is traced from 1964, through their first introduction in 1979, to the present. We review a number of innovations in thin-film technology materials and processes associated with this type of head. Design and technology changes made since 1979 have led to the development and implementation of heads in several successful recording systems. We... View full abstract»

    In this paper, we review many of the technical issues that must be addressed in developing high-quality optical disk recording media. The geometric design of tracking grooves and embossed data on the disk substrate must be optimized to the characteristics of the optical drive to support robust data seeking, track following, and data addressing. To ensure adequate recording performance and drive co... View full abstract»

    Efficient management of cached storage control resources has been important since the introduction of cached controllers in the early 1980s, and it continues to grow more important as technology advances. The need for cache resource management is due to the diversity of workloads that may coexist under a given controller. Some workloads may continually require the staging of new data into cache me...

    This paper describes a document entry system called the Document Recognition System (DRS), which facilitates the conversion of printed documents into electronic form. DRS was developed on a personal computer (PC) with an adapter card for recognizing more than 3000 Kanji characters. It provides a flexible framework for object-oriented management of data and processing modules. The framework allows ... View full abstract»
