Zusammenfassung:	Lessons from research of perpendicular magnetic recording are presented in this paper. The historical view of the developments in magnetic recording teaches us the "20-year rule" for technical developments and the "40-year rule" for technical evolutions. The research work in perpendicular magnetic recording also fruited with a new concept of classification of research work, which consists of three cyclic research models: creation, development, and integration.
