Co−Crビデオフロッピーディスクの実用化検討

抄録

There have been four technical problems to be solved for the commercialization of the Co-Cr video floppy disk (VFD): 1. smooth headtouch 2. durability and reliability under various environmental conditions 3. significant improvement of recording performance 4. reasonable cost. This paper shows that it will be feasible to solve 1 and 3 simultaneously. Regarding 2, durability has been achieved at 23°C, 50%RH and 40°C, 80%RH. It is also confirmed that, by using a narrow track with 10 μm width which is 1/6 of the track width (60 μm) used in the ordinary MP-VFD playback, a comparable video image can be obtained.
