A storage device includes a nonvolatile memory, a volatile memory, and a memory controller. The volatile memory includes a free block management table, and a worn block management table. If the number of free blocks is equal to or larger than a threshold value 1, and errors of the number of equal to or larger than a threshold value 2 but smaller than a threshold value 3 are included in the data read from the nonvolatile memory, the memory controller registers the block in the worn block management table as a worn block. If the number of free blocks becomes smaller than the threshold value 1, the memory controller registers the worn block registered in the worn block management table in the free block management table as the free block.

A picture to be reproduced and displayed on a television monitor () is discerned as a plurality of partitioned areas in correspondence to keys labeled '1' to '9' disposed on a remote control unit (R). After having zoomed in a picture in a partitioned center area by operating a zoom key disposed on the remote control unit, a partial picture in a partitioned area corresponding to a given one of the keys &#x201c;1&#x201d; to &#x201c;9&#x201d; is zoomed in with a desired magnification factor in response to operation of the given key. Position of the zoomed-in partial picture on a full screen and the magnification factor thereof can be visually recognized by displaying cursors correspondingly.

A carbon heating element of excellent durability and thermal shock resistance, usable even in a special environment, for example, even in a strong oxidizing chemical, and having a sufficient capability of generating heat with smaller power consumption. The carbon heating element is formed by covering a carbon material, such as carbon fiber or a carbon fiber cloth with quarts glass, making the interior of the quartz glass vacuous or setting the pressure of the interior of the quartz to not higher than 0.2 atm. with substituted inert gas, and melt-scal the quartz glass.

A novel information reproducing apparatus and information recording/reproducing apparatus capable of searching and selecting information with ease through common manipulations independent of recording media. A recording medium is employed from which start positions of recorded picture programs and start positions of scenes composing each picture program can be read out as data. Symbols corresponding to the picture programs recorded on the recording medium are displayed in an array on a single display screen. A given one of the symbols being displayed is selected, and reduced start pictures of plural scenes, respectively, which compose a picture program affixed with the selected given symbol are displayed in a partitioned array on the single display screen. A desired one of the plural start pictures of reduced size which are being displayed is selected and determined for reproducing the scene corresponding to the determined start picture fully over the single display screen.
