Development of perpendicular magnetic recording conference

The early development of perpendicular magnetic recording and the activities of seven organized conferences on the subject are described. It is recognized that the present popularity of perpendicular magnetic recording is partly based on long and steady activities of the conferences. Valuable lessons from the research of perpendicular magnetic recording are also described. A long period is requested for the development of technologies from an invention to reach worldwide application is mentioned in relevance with the workings of human beings. A new classification of research work consisting of three cyclic research models is presented, which covers the culture as well as academic science and human society. It is concluded that integration is the keyword of all the work.
