DAK ML-90 (c. 1979–1980)

Name: DAK ML-90
Brand: DAK

Little is documented about the DAK ML-90 beyond DAK Industries' own magazine advertising from 1979-1980. No independent test reports or detailed specifications have surfaced. What the surviving record shows is a mail-order blank cassette pitched with unusual candor. The ML-90 was a high-energy 90-minute tape, sold in a ten-cassette risk-free trial at $2.19 per cassette. To move them, DAK's ads openly promised "bribes": free extras worth $35.21, including an LCD digital watch in one offer, so that "your bribe is bigger than your purchase." High Fidelity (December 1979, p.33) and HiFI-Stereo (July 1980, p.23) both carried these full-page DAK advertisements.

The ads concede the competition outright. The copy says the frequency responses of Maxell UDXL or TDK SA were superior to DAK's, and then positions the ML-90 as starting "a technology of protection from Hi frequency loss" - a durability argument, not a straight performance claim. DAK marketed the ML-90 as a budget-friendly workhorse, not a rival to the premium cassettes of the day. Actual measured performance of the ML-90 is not recorded in any source available to the Archive.
