Akai GX-220D


Up to now in manufacturing recording/playback heads, permalloy has been used for making the core and metallic foil has been used for making the gap.

However, for the model GX-220D Akai has developed a glass and Xtal (crystal) ferrite head.

The core is made of pure crystal ferrite in addition to which the inner circumference of the head shield (including the core and the gap) is mounted and set in glass.

As a result, the head is not only dust free and wear free, but produces a focused field (the magnetic field is concentrated into a narrow oblong radius) permitting recording without the weakening or erasing of the signal by the bias current.

High frequency signals can be recorded and regenerated as original sound without distortion.
