摘要 |
A disc recording and/or reproducing apparatus including a signal recording/reproducing section for recording and/or reproducing information signals on a disc 64 mm in diameter housed in a cartridge main body to form a disc cartridge, a loading mechanism for loading or unloading the disc cartridge on or from the signal recording/reproducing section and a control circuit controlling the recording/reproducing operation of the recording/reproducing section. The disc has a signal recording part divided into plural signal recording zones of substantially equal line recording density across the inner and the outer peripheries of the disc. The signal recording/reproducing section, the loading mechanism and the control circuit are housed in a casing which is 70 mm or less in width, 100 mm or less in length and 24.5 mm or less in height and which is provided with a disc inserting opening. The apparatus may be reduced in size without decreasing the recording capacity.
