INFORMATION RECORDING MEDIUM ON WHICH INFORMATION IS RECORDED AS CONVEXES/CONCAVES AND ITS MANUFACTURING METHOD
Document Type and Number:
WIPO Patent Application WO/2008/029787
Kind Code:
A1
Abstract:
A ferroelectric thin film (11) is formed by using ferroelectric bodies having
different etching rates in accordance with polarization direction and the ferroelectric
thin film (11) is etched so as to form a pit (14) having a maximum length value of
1 nm to 30 nm in the orientation direction. Moreover, the depth of the pit (14)
is set so that it is possible to distinguish the electrostatic capacity based
on the polarization direction of the ferroelectric thin film (11) from the electrostatic
capacity based on the pit (14).
