TDK's standard cassette sets a standard some premium cassettes reach for.
TDK's D cassette has improved constantly since its introduction in 1974. In fact, it improved to such an extent two years ago, that it surpassed and replaced the world's first high fidelity cassette, TDK SD. Recently, TDK D improved again. Now it features a Hi-Grained Ferric Oxide particle developed by TDK's engineers, who have also incorporated many of the features of TDK's super precision mechanism.
High frequency sensitivity has been improved by 2.5 - 4.0 dB (from 10 kHz-16 kHz), yielding recordings with a wider dynamic range than some premiums. And maximum output level (MOL) has been increased by a substantial 3.0dB (at 10kHz), to give you more recording headroom with less chance of distortion. Your music will sound great in any mid-priced home deck, car deck or portable.
Best of all, improved D continues in the TDK tradition of quality, with a precision mechanism that will provide years of ear-pleasing performance.
TDK engineers are never satisfied with success. So keep expecting improvements from TDK. After all, a lot of premium cassettes need a standard to measure up to.
