suspect that shrinking something but otherwise the same isn't enough. So, ok, the head lock system is the patent. I thought stereo came some years later, at least it was a lot later when I knew about it. We had a Sony (mono) reel-to-reel recorder when I was young, mostly to send tapes to/from my grandparents. I knew early that stereo tapes were not compatible because of the track arrangement. The in high school years, I got a stereo reel-to-reel (as above, with 1.875, 3.75, 7.5 in/s), and about then knew that cassettes used a different track system, because
Philips required. Reminds me that I also knew that Philips required CD (and CD-ROM) players to only run 1x. The others only came after the patent expired. In any case, the article credits the two-hole cassette to Belgium and Ottens.

issue because the the object may consist of a number of innovations, not all of which are patented inventions. So one usually looks for a reliable source, sometimes a court of law, to figure who really invented the object. To me, at first glance, claims 2 and 3 of US 3394899 appear to claim the CC. I haven't looked at the Ottens patents to see whether what they claim is all or part of the CC, but even if I did this might be OR. I think the best approach is to try and find an RS along the lines of but better than
Bookshop.org. If I have some time I will poke around.

erase head. The cassettes could not be removed from the drive during playback. It was precisely to this detail that the later compact cassette patent registered under the number 1191978 on
January 31, 1964 at German Patent and Trademark Office in Munich has been registered. Peter van der Sluis developed the corresponding recorder. The magnetic head specialist Herman Cornelius Lalesse had the idea of ​​dividing the 1.5 mm wide mono track on a playback side into two tracks for stereo.

process seems far from trivial. Logically, the middle line of the tape which separates left and right sides, should be free of metal oxide and be just transparent plastic carrier, onto which a stroboscopic pattern would be printed at factory - allowing decks to control linear speed exactly via optical sensor. However that's not the case, probably due to cost reasons, so what's the solution?

somewhere how a capstan drive works - the pinch roller system drags tape off the reel at a constant speed, and the drive and takeup spools just provide enough tension to take up the slack...must find a good simple description because I don't understand it well enough to write an article section on it. --

The head locking the cassette is one known invention - the may be other patents we haven't found and/or everything else could be known public art or licensed prior art. The parent allows for other known two hole cassettes known in the art that didn't lock. The question now is what changes if any do

Compact Cassette. Schoenmakers, a member of Otten's team is the named inventor on one patent that has claims which at first glance appear to cover the Compact Cassette. There may be other patents; if we had a copy of Philips' license agreement we would know all the patents that Philips asserted

is says, " Lou Ottens, was the team leader in
Belgium. Involved in the team were J.J.M. Schoenmakers and Peter van der Sluis (the cassette PHILIPS EL 1903, the mechanism, the Recorder EL 3300)." At this point if we consider the "inventor" to be the person named on a patent. I think we have to remove
1181:
Hmm. My first thought is that the head locking the cassette is the least important part. I might have thought the tape width or speed, both of which allow for the small cassette, were the important ones. But then again, are those patentable? Probably not. I don't know patent law all that well, but I
1038:
I suppose, but the one you found is from
Philips Netherlands. I suspect I don't know patent law all that well, but in the case of a corporation, where the invention is by a research group, or even more, the collective work of more than one group, it is less obvious who gets there name on it. As well

I was trying to find the original, or some of the original, patents for the
Philips cassette. Especially with the note above that Otten is the inventor, I thought that would help, but so far didn't. It would be both a useful reference for the article, and interesting related to the above discussion.

I agree with the statement given in response to my HelpDesk question "doesn't sound like a topic for a whole article" yet that doesn't mean that it should not exist at all on Wiki. Although AudioBook was mentioned in the HelpDesk response, the word "Tape" in 'Torah Tape' makes it seem that, wihout

1379:
This article should take care to explain how casette players / recorders keep constant linear tape speed? Since the diameter of providing (unpowered) and receiving (powered) spools change constantly and their diameters are unknown, due to existence of 15 to 120 and even 180 minute casettes, the
1430:
Constant linear speed is not specific to Compact Cassette transports, but to all tape recorders. It is true that the lowest-end reel-to-reel machines did without it, but anything better had to have linear speed. Enter the capstan and pressure roller combo, as early as the first Magnetophones.
1321:
Over the next few weeks I plan to restructure some of the sections in this article. Particularly in the "Cassette types" section, I would like to add some subheadings to differentiate between each type to allow for better user readability. Feel free to leave any suggestions or questions here.
1395:
What makes you think cassette tape recorders bothered to keep constant linear speed? The ultra compact pocket dictation machines just dragged the tape through willy-nilly, relying on playback on a similar machine to keep the voice recording intelligible. But you are right, we should describe
1114:
claiming some aspect of the Compact Cassette. Where the patents were issued is irrelevant; Schoenmakers is in at least two jurisdictions. So in the end we are left with "Otten led the team that developed the Compact Cassette with a member, Schoenmakers, patenting one aspect thereof.
1061:
says above, anyone in the group who contributed to the invention is legally required to be listed as an inventor on the patent. Otten still may have contributed to critical aspects of the cassette that were not patented and so could still be considered an inventor if that is the case.

in the variety of sound recording media. It would seem that there could be an article on the production and sale of prerecorded audio media, including prerecorded cassette tapes. In a quick search, I didn't find one. I will try discussion in

Reminds me of all the discussions about the invention of the transistor, and especially Shockley. When it is not a lone inventor, it is harder to figure out who to name. But Ottens does have some patents, which was part of what confused me.

for this article which does not have a single instance of any other type of recording content. If Torah Tape is worthy of its own article, that should be discussed but not here. Accordingly, I am deleting the section.

This supports Schoenmakers as the inventor of the CC in that the primary innovation was using the recording mechanism to lock the CC to the recorder. Whether this is enough to put it in the article is another question.
