This was found in the forum reader, I'll update with the original poster if I can find it. I saved these beautiful scans, while most manufacturers were cranking out crap, AIWA still had a huge line-up. Around 1992, minority share holder Sony gained majority control and turned the line into a budget offering, a sad fate for a great cassette player manufacturer.
Wow this catalogue brings back some very pleasant memories, I had the HS-JX101. I wanted to try the HP-V99 earphones but could never find one.
There's a ton of brochures in the "forum reader" link, unfortunately sometimes when you search them through google it only gives a link to the graphics file. I wasn't the original poster, thanks to whomever put it up!
How did this bi-azimuth head alignment work? Was is it pure electronics that made it happen, or a plunger/actuator?
A few years later, I picked the ultra thin Aiwa HS-EX2000 out of such a catalog. Amazing device, except for this proprietary lead acid gumstick battery. Good to have cheap battery alternatives nowadays that actually get you through at least half a day of use without the large external 2x AAA battery holder.
Making smartphones are much easier than these tech packed electro-mechanical devices. Software will do everything! Sadly missing the original Aiwa.
Off-topic: From the Sony catalog I purchased a micro hifi set. Still going strong after 20 years, but now it needs to go: I never cleaned the head and capstan before, but today I did and was surprised that the rotating record/playback head made it into the cheaper range: If someone has this catalog, I would appreciate a link! Okay, back to the topic.
It looks like other brands like Sanyo had a similar configuration, although not marketed as bi-azimuth adjustment: http://stereo2go.com/forums/media/sanyo-jj-p4-14.1650/full
Amazing the features packed into these things, and with higher quality than most full-sized boomboxes
