Preface This book presents an approach of Pansystems Community to modern magnetic recording and optical recording. The International Pansystems Community has worked on Pansystems Theory founded by Professor Wu Xuemou for the past 24 years. I joined this naturally formed academic community 10 years ago by promoting Modern Pansystems Engineering. In this book, magnetic recording and optical recording is treated as a unified discipline called magnetic-optical recording (MOR). A pansystems view of magnetic-optical recording is then gradually unveiled through discussing topics of magnetic recording and optical recording in my own way. A series of concepts about magnetic-optical recording (MOR) are formed, described and discussed which include generalized system, generalized relationship, pansymmetries, transformation of pansymmetries; generalized hardware(pan-head including things like HAMR heads, pan-media including things like HAMR media, pan-direction recording, pan-layer recording, pan-contact, pan-relative motion, generalized recording channel, etc.), generalized software (theories, methods, principles, pan-design, etc.), transformation between generalized hardware and generalized software(softened hardware or pan-ware); interactions inside write/read process, among element technologies and between optical recording and magnetic recording (neuron-like mechanism); uncertainty of generalized recording channel, observacontrollability of instability of MR/GMR/TGMR/EMR head, and the generalized equalization optimization for PRML and other advanced channels. I am going to begin this book with the discussion on vector analysis, Maxwell's Electromagnetic Field Theory, and other mathematical foundations. I then try to integrate the original treatments of the up-to-date, standard and popular books on magnetic recording and optical recording with the pansystems view. It should be emphasized that I have learned so much from those great books on magnetic recording and optical recording in the past 16 years. Without the learning experience and my special and exciting experience in both academic society and industry of information storage technology, this book would never come into being. At the end of this book, I would like to discuss the general picture of Pansystems Engineering for the upcoming 21st century. The task of Pansystems Engineering as a whole is to present a uniform Internet-like theoretical platform to link all of the high-tech theories of 20th century together, and describe them all with typical style and universal language of Pansystems Theory. The Internet provides a brand new environment for people of 21st century to express their own ideas. People can be the "International Publisher" of their own work, and the time interval between the "1st edition" and "2nd edition" could be very short. The "book" becomes an active and dynamic information ! The reviewers of the ideas are not 1, not 2 but thousands of people--- the visitors of web site. This would save a lot of time and money to publish ideas compared with traditional publishing systems, and would give new ideas a most reasonable assessment because that is from God --- the readers . I also kept in mind the intention of promoting publishing new ideas through Internet when I began to think about writing this book. May my readers love this book !
