JTS Corporation was a maker of inexpensive IDE hard drives for personal computers based in San Jose, California.

It was founded under the legal name JT Storage, Inc., but traded as JTS Corp.[1] A few months after its foundation, Pearce departed the company, with Tandon filling his role as president.

Eventually, as 2.5" drives became cheaper to build, interest in the 3" form factor waned, and JTS and WD stopped the project in 1998.

After Kalok failed in 1994, JTS hired its founder as their chief technical officer, and licensed the patents involved from TEAC and Pont Peripherals.

[7] On February 13, 1996, JTS announced a reverse merger with former video game and home computer manufacturer, Atari Corporation.

However, with the failure of its Jaguar game console, losses mounting, and no other products to sell, Atari expected to run out of money within two years.

On two occasions in April, JTS staff were laid off including some former long-time Atari individuals, and the company was soon forced out of AMEX.
