Abstract: The present invention relates to a recording apparatus for improving operability of a DVD camcorder that performs recording in a video format. When an instruction for starting recording is given at a time T11 and then an instruction for stopping the recording is given at a time T12, a DVD camcorder is brought into a pause state at the time T12. An address and the like of an optical disk at that time are stored in a recording RAM. When an instruction for resuming recording is given at a time T13, the address stored in the recording RAM is read, and rerecording is started at a position on the optical disk which position corresponds to the address. The present invention is applicable to DVD camcorders.

Abstract: A polyimide composition is prepared with a polyimide containing minute hollow spherules made of a glass of a hydroxyl group content and having less than 0.5 mg/m.sup.2. A multilayer substrate for printed-wiring is prepared with this polyimide composition. The substrate possesses a low dielectric constant, dielectric dissipation factor and thermal expansion coefficient.

Abstract: A polyimide composition is obtained by adding triallyl isocyanurates to polyimide, preferably with further addition of an accelerator and diluting solvent. The composition is made to show effective reduction in dielectric constant as well as in the inherent viscosity and surface tension so that, when employed in manufacturing laminates, the degree of impregnation into base material can be elevated to remarkably improve resin filling.
