The present invention relates to a recording medium cartridge memory and recording/reproducing apparatus. A recording medium cartridge consists of a recording medium and a cartridge memory in which a unique ID of the apparatus used for recording/reproducing the cartridge memory is recorded in an unrewritable condition. The apparatus for recording/reproducing the recording cartridge memory consists of a sending/receiving unit which reads out an ID recorded in the cartridge memory, an ID inspection unit inspecting whether or not the ID recorded in the cartridge memory and an ID stored in the apparatus accord by comparing both, and a control unit which records data in a recording medium or control operations of a recording/reproducing unit which reproduces data from the recording medium based on an inspection result in the ID inspection unit.

An image forming apparatus having a display panel with 1,920×480 electron-emitting devices arranged in a matrix and a plurality of fluorescent substances for emitting light by electrons emitted by these electron-emitting devices includes, as one of circuits for driving the display panel, an I/P converter for converting an interlaced scanning signal input at an NTSC image frame rate by a double frame rate and converting the signal into a non-interlaced scanning signal. The signal is controlled to define the maximum time interval during which the fluorescent substances are continuously irradiated with electrons from the electron-emitting devices in units of rows in line-sequential scanning, so as not to substantially degrade the linearity of the luminance characteristic of the fluorescent substances that changes depending on an electron irradiation time for the fluorescent substances.
