       | I have not one but two Data Discmans, unfortunately neither

       | (correctly) is a bigger task than I'm interested in at the
       | moment. I'm going to have to see if I can get the emulator
       | running and try out the discs I have.

       | The Data Discman fascinated me ever since I first saw mention of
       | it in a magazine. This was the early 90s so CDs were still
       | Brobdingnagian compared to other storage media at the time. A
       | portable device that could carry an encyclopedia? Amazing! To me
       | at the time they were a Star Trek technology made real.
       | 
       | As an aside I still love Sony's consumer electronics industrial
       | design from the 90s. It was a great intersection of functional
       | and attractive.

         | There is authoring software available at
         | http://www.robotsandcomputers.com/computers/dd8h.htm to create
         | compatible CDRs full of books assuming you can find some blank

       | Those applications seem pretty weak. In a similar timeframe I
       | seem to recall possessing a standalone dictionary/crossword
       | solver device, and a five-language translator/dictionary. Both of
       | which were much more compact and presumably had small, solid-
       | state data in ROM chips. The monochrome, text-first Data Discman
       | software looks similar to the output of those basic devices.
       | 
       | I suspect the problem with the Data Discman was weak multimedia
       | capabilities, compared to the what can fit on a CD-ROM, in either
       | its API or what the hardware could push. If the software of the
       | Data Discman had been more like Microsoft Encarta, it might have
       | wowed people.

       | CD-R and it would have filled an immense need to replace floppy
       | disks at the time (I love vintage and nostalgia, but floppies had
       | way too much io errors, and the speed was.. not really there).
       | 
       | Maybe there were real technical reasons why data MD drives never
       | caught up (too much cpu power required to handle the data ?) ..

         | recorders, and I couldn't justify getting a data drive when I
         | already had a recorder. Back in the 90s I always assumed that
         | was because Sony was paranoid about piracy; I even had to buy
         | some kind of device so I could record digital audio from my
         | computer directly onto audio MDs. (If I recall correctly, it's
         | been a while!)

         | 
         | The technical reason why MD Data never caught on is the same
         | reason why Iomega Zip and all the other superfloppy formats
         | failed: none of them beat the CD on storage density and media
         | cost. By the time the market actually needed a successor to
         | 1.44MB floppies, everyone also had internal hard drives, so a
         | lot of the use of the floppy drive was to install software. The
         | fact that CDs couldn't be written to (yet) didn't matter. The
         | fact that they held 650MB made them mandatory equipment, while
         | every other rewritable medium was just a luxury for
         | professional users working with a lot of data. And CD-Rs and
         | RWs killed that last niche, too, even though they were less
         | convenient[0] than superfloppies were.
         | 
         | [0] Writable optical media is a bit of a hack, necessitating
         | processes like "mastering" and "finalization" to try and make
         | the writable disc look like a regular disc to drives and
         | players that aren't aware of the rewriting process.

           | 
           | I wouldn't say Zip didn't catch on, there were a few years
           | where Zip drives were pretty ubiquitous. MD Data had a price
           | problem. The drives were expensive ($500+) and the disks were
           | nearly $30 IIRC. Meanwhile a Zip drives and disks were half
           | that or less.
           | 
           | On the whole they just did not offer enough storage over
           | competitors to justify their price. When CD writers got cheap
           | they were better in almost every way.

       | 
       | Anyway... that was a preamble... in 2001 I spotted some of these
       | in a weird shop in London near Russel Square. They had a sticker
       | price of PS150 which I thought was absurd. In one of my very few
       | attempts to haggle in my life, I offered PS50 and the shop
       | attendant turned me down flatly. I was mildly disappointed
       | because they were so brazenly "alternate timeline cassette
       | futurism" (before the latter term existed) and the thought that
       | I'd missed a golden opportunity gnawed at me for years. At some
       | point in 2002 or 2003 I went back, but the stock had gone. I
       | doubt they sold any of them at that price in that age.
       | 
       | Anyway, I probably dodged a bullet. They looked cool though.
