Thanks for posting, ITFreeTraining !!! You get my Thumbs Up, for this informative video & the hopes that it gets moved up the list of relevant videos on RUclips. If you see this, I have a question: with the increasing density of data storage on discs, what are your thoughts on using another layer cover besides polycarbonate plastic?
Thanks for the thumbs up and watching the video. It is an interesting question, however due to optical media losing so much market share the research and development is not there anymore. So we may never see new materials tried.
Really enjoy your vids, and great to see that you are adding some new ones recently. Have you ever thought about doing an entire series for the current series comptia A+ certification exams, 1101 and 1102?
Did CD and DVD use different laser wavelengths? Yes. Can you tell that out of this video? No. Also DVD-RAM had some use in data archiving. Besides this couple of points the video is fine teleport to some retromedia world which I miss sometimes.
In a different video we talk about the wavelengths, but I think you are right we did not mention in this video and it is an important point. We need to re-do this video for the new course so will have a bit more look into DVD-RAM and adds some information for the wavelength. Back in the day it did not get that use that much compared with the other media. Thanks for watching and the feedback.
@@itfreetraining thanks for the reply and for the whole video series! If you plan an extended optical media then some mention on hd dvd is highly expected there, it lost the format war, but still was a big thing. Also dvd audio and sacd could be mentioned, they didn’t make any great sales but they made a foundation for today’s hires audio standards in medialess content distribution. Maybe even some extra short comparison on codecs of written content, otherwise it’s not obvious what changed between bd and 4k bd.
As a Gen Z guy, I still use dvds/ blu rays a lot, but thats probably just my love of physical media over digital files/ streaming.
Nice to hear. There are something special in the old days to show of the DVD collection.
Physical copies cant be taken away, so that's a big plus for me.

Glad you like the video. We are currently working pretty hard on the 1101 course and after that will start the 1102 course.
a great way to keep secret files (along with floppys)
True, it starting to become that people won't have the hardware to read the media.
In case of DVDs the DVD-R is DVD dash R not DVD minus R
Dual layer DVD would be like the old 8 track tapes switching tracks. My age is showing.
I never did any work with the 8 track, but I know about them. I guess my age is showing to.
