So I was Bored...

I decided since I had nothing to do today... I opened up my computer case, and ripped out my BR and HD DVD drive... Well I decided to crack both open, to find out what looked to be very similar lens and lazer assemblies... Hmm, So I further dismantled them to remove the trays, which are very similar as well... Well wouldn't you know it the circuit boards are similar as well. The difference being in the chip designs... They were both using samsung chips. Different model numbers on them. I think there memory, because I did a search on the web, and it kept poking me in the direction of 512 and 1mb caching memory? Similar ships used in the ipod... weird. The other chips looked like processing or buffering processors... Anyways, I'm going to investigate a bit more... Did I tell that I was bored...

Great information for those that don't even own a screwdriver...

Maybe there is a way to convert HD DVD players to Blu Ray, and back again with common kitchen items, or $5 worth of parts from Radio Shack.

Would be cool to find that all of the HDM machines are made in the same plant in China, and are all the same machine internally, the differences being the external housing and cosmetics.

The only differences between the 2 formats is that Sony turns the same adjustment screw 3 times but Toshiba turns it 7.

VideoCipher... all we need to do is send the player, a paper clip, straw, rubber band, roll of toilet paper, piece of string, and a small coin to MacGuyver... and he'll do it for us.

Mike you forgot the Bazooka Bubble GUM. LOL

Naa, I put them back together. I was a little worried when the BR door wouldn't open at first!!! Now I got it back together... whew. Oh by the way the BR drive is made by Samsung, but it doesn't read samsung on label... And the Toshiba drive, the board is done by Toshiba and the optical assembly is the same part # as the BR drive made by Samsung... The HD lazer pick-up is from NEC. That clarifys some stuff. Oh Lazer stuff is made in Japan for the Toshiba, and China for BR. The boards for Toshiba in my unit anyways was done in Japan, and the Assembly in China. The BR board is done in Korea, and the assembly in China... Thought I'd point those out to you guys... Not like it matters anyways...

the lasers have different focal points. it is impossible for either of them to read other discs unless the lasers are somehow adapter or switched even in a combo player.... anyone own one that wants to open it up for us?

Camera lenses have done this for years, a very simple adjustment and little known about control adjustment code named "Focus".

Oh Jeeez, HD DVD players can become Blu Ray players, and Vice Versa, with a simple firmware update.

Both format players being manufactured in China, probably in the same building, and on the same assembly line as well...

It's not a matter of simple focus. HD DVD and Blu-ray are completely different technologies - with HD DVD being closer to standard DVDs which allowed them to use a lens with similar numerical aperture. The "reflective pits" are packed closer together on Blu-ray, and they had to increase the numerical aperture of the system. The data (those "pits") are even physically encoded differently on Blu-ray disks for additional capacity, and this also requires different electronics at the pickup end. All these physical differences mean that new replicating plants had to be built since standard DVD lines could not be converted for pressing the Blu-ray format. And it also means you can't play a Blu-ray disk in an HD DVD player (or vice-versa).

And Philly Cheese Steaks are made in Philadelphia!!! LOL

InvisibleBiker, I bet you didn't know that "Buffalo Wings" aren't real buffalo wings - but chickens. That's why they taste kinda like.. well... chicken!

LMFAO!!!!!!!

And guess what, they originated in......... Buffalo!!!!!

InvisibleBiker, many years ago a few friends phoned me up one morning and invited me to drive to Buffalo with them on the sole quest of finding this original restaurant where Buffalo wings were made famous. The whole adventure was like something out of the movie "Harold & Kumar Go to White Castle" with the journey holding more "mis"-adventures than I care to remember. When we finally got there, we didn't know if we were at the right place or not. But the wings we ordered had "soggy skin syndrome" and weren't spicy enough. I went with the same friends a week later to Montreal for the sole purpose of finding the famous "Montreal Smoked Meat on Rye" place!

It might sound pretty dumb in retrospect, but oh man, those were the days.

those are the adventures that make life worth living


on topic, its not shocking that likley 75% or more of both drives are the same stuff. They just read differently and I'm pretty sure someone tech savvy enough could probably fiddle enough to make one read the other. Like how they mod gaming systems.

Sky not at all, when I was in college back the late 80's, we had a many road trips. They are part of what makes our lives special, memorys that will last forever.
So were the soggy bottom wings from the original wing house or not? LOL

To be honest, to this day I really don't know

But the best wings I had ever was during a trip going to Nova Scotia from Ottawa. We had to pee and stuff, so I took a random exit off the highway in some God forsaken little town in the Quebec heartland. We all felt a little hungry, and noticed a restaurant complete filled with cars just on the main street (likely the only street in town). They had these wings that they baked or something after frying and rolling in the sauce until the sauce was basically dry with the skin all crispy. And man, were they spicy hot! That's why everyone in town was there. Since I never took notice of the town's name at the time, I was unsuccessful at ever finding the place again when making the trip across the province.
