Kalok was a hard disk drive manufacturer which went bankrupt in 1994.[1]

One of their last offerings was a 100 megabyte 3.5-inch disk drive using a stepper motor head actuator (rather than the servo-based voice coil operated actuators used on most drives of that density) and was very limited in both access speed and reliability. The drive was manufactured in India, and was commonly found in very inexpensive generic PCs.

In the early 1990s, Kalok also designed hard disks for TEAC[2][3] who used them as part of a removable hard disk drive system,[4] which was also sold under the Kalok name. After Kalok failed in 1994, JT Storage (JTS) hired its founder as their chief technical officer, and licensed the patents involved from TEAC and Pont Peripherals.[5]
