An optical information recording medium has a first information recording layer (20) and a second information recording layer (40) each of which includes (i) a group of pre-pits (31, 51) constituting marks (32, 52) and spaces (33, 53) and (ii) a super-resolution film (23, 43), the marks (32, 52) and the spaces (33, 53) having different lengths, an average length of a smallest mark that is smallest in length and a smallest space that is smallest in length being less than or equal to a resolution limit of a reproduction optical system for reproducing information recorded on the first information recording layer (20) and the second information recording layer (40), the group of pre-pits (31, 51) being formed so that a push-pull signal for the reproduction optical system to reproduce the information recorded by the group of pre-pits is negative in polarity. This provides an inexpensive and high-capacity multilayer optical information recording medium based on a super-resolution technology..

Organic light emitting display
An organic light emitting display includes a display panel including data lines, gate lines crossing the data lines, and pixels and a panel driving circuit which supplies a data voltage to the pixels of the display panel during a power-on period and then is additionally driven for a predetermined power-on delay duration time delayed from a power-off start time of a power input signal. The panel driving circuit supplies a reverse polarity recovery voltage having a polarity opposite the data voltage to the pixels or supplies a recovery voltage, which is different from a gate voltage of a driving element of each of the pixels, to a source terminal of the driving element of each pixel for the predetermined power-on delay duration time..

Magnetic resonance imaging apparatus and correction value calculation method
In order to obtain a high-quality image even in multi-slice imaging in a ute sequence that uses a half rf pulse, a refocusing pulse of the slice gradient magnetic field is adjusted and applied so that the excitation profiles of positive polarity data and negative polarity data have phase distributions that are 180 [deg] inverted with respect to each other in side lobe portions. In addition, the irradiation frequency of the half rf pulse is adjusted so as to eliminate a position shift between the intensity distributions of the positive polarity data and the negative polarity data..
