Is the tip on the smaller laptop hard drive read head rhodium like the end on the larger hard drive?

TLDR: yes

The metal is one of the more common ones chosen for magnetic read heads.

The smaller and more condensed the platter tracks the more likely you are to have rhodium.
I won’t pretend to understand the how and why of this scientific aspect but the more precision needed the better rhodium works over other material cores.

Again we’re talking very tiny amounts.
However there are two groups of users here that could benefit from holding on to it. Especially because boardsort doesn’t do anything special with drive arms with or without the heads.

Some of the companies here have the volume where even dirty-slicing the ends off could add up to a refinement shipment quick enough to be worthwhile.

Hobby Refiners.

You’ll need a few hundred heads to even begin contemplating either task but it’s still good to know.

I just got about 50 laptop hard drives that someone took them apart for the discs. They left the read head and the board attached. Leaving me with the best of everything from the alum. case, to the circuit board, to the read head.
Which leads to the next project hopefully soon. It should be worth saving the read heads from these:

Bins measure 28"long x 18"wide x 15" deep with approx. 20 drives per layer.

Lmao on this on! I love it when people take the platters and leave the boards.
There’s a reason boardsort pays less for platters than standard aluminium.
For one thing nearly half of all platters are GLASS!!!! Look it up.
I’ve politely corrected quite a few yards over the years buying platters as high value aluminium. The myth of value continues on anyway!

That’s a lot of heads though. And a lot of boards!
I’ve noted elsewhere that the heads are not clean. By any stretch.
Be it a rod or pad rhodium is a tiny fraction of a fraction of the total head weight.
So it takes quite a few pounds of read heads to make a refinery interested.
I’m not sure what the actual ratio is or pricing at the moment. But with rhodium in the very low 5 digit value right now you don’t need much to get a few hundred bucks. You’re definitely in the quantity range there to get someone interested.
