"Seagate is launching their 16 TB CMR (conventional magnetic recording) helium drives today under two product lines - the Exos X for datacenter usage, and the IronWolf / IronWolf Pro for NAS units. The company has been actively shipping the Exos X drives to hyperscale customers, and today's launch is geared more towards the retail market. Similar to the currently available 14TB drives from Seagate, the new 16TB variants also use TDMR (two-dimensional magnetic recording) technology for the heads"

It's nit clear howtthe 16TB drive is achieved, e. G. Additional platters. The weight is the same as the 14TB and the transfer rate is the same.

Presumably, that's possible. An odd number of platters is still an even number of sides.

I don't know off hand how their dual actuator drives are supposed to work, so I don't know how they're tackling these kinds a issues.

Seagate has had a history of using multiple heads at once (Barracuda 2HP).

One could look at recent patents filed by / awarded to Seagate to see if there is anything publicly available about how they are handling it.

That's not feasible with drives for two decades. The Seagate supposedly works like this with each actuator handling a portion of the platters.
