LD (Laser Disk)

The accepted abbreviation and terminology for 12 inch consumer playback only video laser disks (and also 8 inch disks recorded using the same format). The video recording is of a composite video analog signal with about 5.3 MHz of luminance bandwidth which gives a maximum horizontal resolution of 425 lines. There are two analog soundtracks and two digital soundtracks; not all players can play the digital soundtracks. All players can play both the CAV and CLV disk formats.
