A Hitachi promotional cartoon in the style of Schoolhouse Rock explaining perpendicular magnetic recording for hard drives.
Remembered fondly as a fun, memorable animated explanation of how perpendicular disk storage works.

That song is etched into my memory and bring back a flood of great feelings. Daily Motion is giving me a playback error, but here's a copy from youtube: ▶ this video
maybe not CS concepts, but wanted to re-share Perpendicular disc storage from Hitachi. ▶ this video It's a simple concept to explain, but animation sure makes it fun and lasting.
That's what I'm wondering though. Nearly all the WD data center drives are marketed as Ultrastar. Is this marketing, or did the HGST entity supplant WD enterprise during "integration" in the last two years? link It looks like the only surviving product names are Ultrastar and CinemaStar. Nothing is labeled HGST anymore. Most of the HGST Helium disks were SMR, if I'm not mistaken. As of now, given the two HelioSeal series, one of the two is SMR. Side Note: Hitachi had such a great thing going with their Schoolhouse Rock meets Dino DNA commercial. I wish this would have continued. ▶ this video
> or if we radically change the fabrication process and turn transistors sideways This reminded me so much of this: ▶ this video
Maybe you forgot this? Hitachi School House Rock video... ▶ this video "Get Perpendicular" Hitachi Global Storage Technologies.
