The company focused on the production of 2.5-inch cartridge hard disk drives, initially through computer system builders as an OEM and, later, directly to customers as a vendor.

Avatar contracted Hoya Electronics for manufacture of the platter, which measured 0.025 inches (0.64 mm) thick and was fabricated out of glass-ceramic coated with a thin magnetic film (1600 oersted).

[10] In January 1996, they secured their first new design win in two years with Acer, who offered Avatar's new 130-MB removable cartridge hard drive (rebranded as the HARDiskette) on some of their laptop models.

[12] In March 1997, Avatar released the Shark 250, an external removable hard drive system featuring the company's newest 250-MB HARDiskette.

[15] Avatar later offered a PC Card adapter for the Shark 250, allowing laptop users to obtain better transfer speeds.

[16] One major design flaw suffered by the Shark, mentioned in its manual, is a catastrophic failure of the head assembly should the drive reader unit be transported with a cartridge installed.

[17] Avatar filed for Chapter 7 bankruptcy in October 1998, leaving numerous late adopters of the drive irate that a $50 rebate offered earlier in 1997[18] could not be cashed in.
