Guess which model walkman this head goes to?

Yes, this is the Phillips DCC 170. It's a DCC walkman: Digital Compact Cassette. It was a format developed by Phillips that allowed dgital recording on special tape.

It was released to compete with Minidisc and made recording with a lower compression that it (4:1 to 5:1). what made it special whas the compatibility with standard tapes.

My DCC 170 sounds incredible, comparable to a Minidisc. It has a bass amplification that sounds so good!

It's a philips 130 DCC player, the 170 has the metal cover inside of the door, but close enough, Photo that was crop from.

DCC used a magneto resistive (MR) head, In portable DCC player/recorders the head assembly consisted of two 9-track DCC heads (and two erase heads if the device was capable of recording) Because of the low tape speed, the achievable bit rate was limited. Nine heads were used to read/write half the width of the tape; the other half of the width was used for the B-side. Eight of these tracks contained audio data, the ninth track was used for timing and text information and for markers to indicate the start of a song or the end of a recording, how it come up with the text info.

The fixed assembly for portable recorders was more difficult to make and gave lesser sound quality (especially dynamic range) when playing analog cassettes, so lack some detail during analog playback, which the full size home recorder, used a flip head design, which would flip the entire head assembly around by 180 degrees when the B-side was played or recorded, but was much better as they used a combination of a 9-track DCC-head with a 2-track analog stereo head, for playback of analog tapes.

I feel a game coming on

Here goes some photos of my DCC 170 unit, which I find so cool.
