Akai X-100D


Using the cross-field head, the model X-100D provides a surprising recording performance.

What is superior about cross-field recording? How does it differ from typical recording methods as far as construction is concerned?

In the cross-field system, the signal current is applied to the recording head while the bias current is applied to the bias head.

These two heads are located in different positions, as determined inter-relatively, so that the magnetic field of the bias will not affect the signal recorded on the tape, even a sufficient bias is applied.

This allows the recorded signal to remain on the tape with high fidelity.

Just picked up one off Ebay for less than 50 bucks. Listening to Peter Paul and Mary - Album tape, nothing short of amazing. Going to have to tune up the transport mechanism a little, has trouble rewinding tapes, otherwise ok. Better than vinyl, a little. Love it.
