The Titanium Video Disc (TVD) is a analog disk storage invented by Theorysonic in 1984 and released in 1985. The medium was mostly used for recording, store any kind of data and watch video programs on TVD players. TVDs have a higher storage capacity than 3 ¹⁄₂-inch floppy disks while having the same dimensions.

The average size of the TVD is 256MB (approx. 30 minutes of footage), compared to the high density 3 ¹⁄₂-inch floppy disk. which had 1.4MB of storage. TVDs also came with 128MB, 64MB and 32MB, which were made for the cosumer market while 120MB is only used in prerecorded disks, which came ranging from 4 to 12 disks, depending on the size of the footage.

In the 1990s, high density TVDs were made and it can hold from 512MB to 2GB of storage

Sales of TVDs declined in the late 1990s following the introduction of the DVD. In 2001, Theorysonic announced production of standalone of TVD players were discontinued while pre-recorded TVD disks were continued to be made until 2003. However, Meroview continued to made blank TVDs and TVD players until 2009.
