What SD CARD should I buy?

If you want an SD Card for your camera - these are the ones I use and recommend. 

I'd strongly recommend not to buy any SD cards off ebay - I've heard about too many issues with counterfeit cards - often sold on by unwitting resellers. My inbox regularly gets messages from people who bought a £150 camera then cheaped out and bought a £3 memory card on ebay - Then when it doesn't worth they blame the camera! It doesn't make any sense. Good memory is cheaper than it's ever been - see the links above.

A lot of HD cameras will not work properly with cards larger than 32GB (cards over 32GB are usually SDXC rather than the SDHC standard used by 32GB cards. SDXC cards use the ex-FAT system rather than FAT32 - in short they are a different standard). - so don't just buy the biggest card you can afford - read the specs in the manual to see what it accepts.


RECOMMENDED CARDS (for action cams - see dashcams below)

CLASS 10 UHS-1 CARDS (For HD Cameras)


U3 CARD (For 4K cameras)




The SD card in a dashcam is re-written over, more frequently than in other types of cameras. Some manufacturers void their guarantee if an SD card was used in a dashcam. So, no surprise, there are special High Endurance SD cards made just for's some.


VERY IMPORTANT. These links take you to the product, however Amazon have three different ways of selling. There's Amazon Direct - This means that you are only dealing with Amazon themselves, then there's other sellers that use Amazon's facilities - these show as Fulfilled By Amazon and finally there's Market Place sellers that advertise on Amazon, but operate independently.  I strongly recommend that you only use the first...the Amazon Direct - Sold By Amazon option. Even if it appears that you are paying a couple of £/$ more it is more than likely you are comparing the price of a real item against the price of a fake.

To give you an idea of the extent of the fake goods problem. In a 2016 survey by Apple - 90% of the 'Apple' chargers sold through Amazon - using the other the two methods..which includes the "Fulfilled by Amazon" option -  were found to be counterfeit....90%!

Retro Tech: The 3M Cantata 700 Background Music Machine

Another delve into unusual audio technology from the past. In this video I take a look at the 3M Cantata 700, a format that boasts the largest music cartridge ever made.

If you think 8-track tapes were a bit bulky, wait until you see this. 

If you want, you can CLICK HERE to download a 1hr MP3 of Music recorded from one of the Cantata tapes (I forget which one). This is all I am able to capture at the moment as the machine has now taken to chewing up tapes and making horrible rattling noises.

It makes PLENTY of sense - but I did put the folder (CantataBGM) on 'Share' after moving file 3M002 into it. From your reply I now assume that each file must be 'Share'd individually?...even when all files are in the folder? Hmmmmm....OK, I'll do that. The folder has 6 files in it at present, with many more to come.

All 6 files are on 'Share' now, hope it helps.

Thanks Ralph that's great, they're all there now.
I think quite a few people were interested in having the full tapes as a long 26hr(?) recording - did you keep any like this?

May 26, 2016 | Registered CommenterTechmoan

Yes, I kept all 6 of the Cantata tapes that I bought - Rhythmic R165 and R266, plus the Christmas tapes Rhythmic RX266, Melodic MX266, Christmas Vocal VX167 and Continuous Christmas CX167. From them I recorded at least 95% of the total onto 15 reels of Scotch #150 - 1 mil, 3600 feet each on 7" reels - and two hours of the music is further recorded on cassettes that I created the files from. Concerning a complete Cantata tape of 26 hours duration, I'd best leave that project for someone else because so much of the music - especially on Rhythmic 165 - is below average. Rhythmic 2 is MUCH better in overall orchestration !! R165 does have SOME really worthy orchestrations, so I'll include them in the file total as I fill the folder. The songs I choose for the folder are among my true favorites, so you'll get an overall impression of Yours Truly; by the 6 files you heard now, you have a head start.

Thanks again Ralph, when I get a few minutes I'll update the blog entry and add details about how to download your files.

Techmoan, have you noticed something odd about this Page 2? So far it's just you and me !!! The other commenters are still back on Page 1. Okay, I added four more files to the folder, 3M006 through 3M010. More coming tomorrow.

May 28, 2016 | Unregistered CommenterRalph Baker

Ralph - thx for your efforts, I was waiting until you figured out the mysteries of file sharing. Your compression on the files is a bit odd but works well enough. I can't imagine that those tapes had much dynamic range to begin with but the effect is a bit ethereal. A Swedish musician "Musette" authored a couple interesting albums by sampling old, lo-fi reel to reel instrumental tapes. My favorite is Drape Me In Velvet. He'd likely have a field day with these Cantata tapes.
I was hoping to have a longer upload of any Cantata tape, unedited in the original song order but this will do for now. I wonder when the last actively used Cantata machine finally had its plug pulled? I hope they had a ceremony.

Hey David, you finally caught up !! As background music the recordings were lower 'Fi' than the machine is capable of; you heard the music on the factory paging system but were not distracted by it. That is very intentional in the music's arrangement and creation. I was one who DID pay attention to it during coffee breaks or the half hour lunch break, and I liked the music so much that I bought a Cantata700 in early 1970. I had it until 1998 when I couldn't get the pinch rollers any more unless I paid a king's ransom for them. No thanks !!! So I gave the machine to a repair shop but kept the tapes, re-spooled onto 10.5" NAB reels. Concerning the present, there are Cantata 700s still playing to this day under attentive care by users who genuinely see future use of the units.

The next four files are in the folder now, 3M011 through 3M014. I have a 5th file ready, but the folder didn't take it; a red bar appeared in the progress line along with a message "Error: Upload Interrupted". Does this mean that I used up my free space allotment?? The readout says 86.?% of whatever space there is, but it indicates 1% of 10 GBs of space. If I must delete 1 or 2 files to make room for additional files, I'll do that....but PLEASE get copies of the files available so far. I don't want you to miss ANY of this great music !!!

This is such a great review! I've been streaming the mp3 though my McIntosh Hifi from my phone. The quality level is perfect for the subject matter. If there is any way for you to get the whole tape on or some of the others, it would totally annoy my family. I know you are up to the challenge. Wonderful job as usual!
