Tiny Media, revisited
A few weeks ago I posted about getting a tiny cassette tape and commented that I needed a microdrive to complete the collection.
Clockwise from top: a 36 exposure film cartridge for a Minox camera (takes 8 × 11 mm pictures on 9.2mm wide film); a US dime and green a Lego brick of the most generic type (3001, 31.8 × 15.8 × 11.4 mm); a Seagate 4GB microdrive in Compact Flash package (43 × 36 × 5 mm; platter is 26mm Ø); a 120 minute Sony NTC-120 cassette tape (30 × 21.5 × 5 mm; 2.5 mm magnetic tape) and a Samsung micro SD card (15 × mm × 1 mm).
I checked ebay, and microdrives are easy and cheap to find these days, so now I have one. Upon getting I found out I had to buy a new Y000 size tri-lobed screw driver (well, bit for my modular driver) to take it apart. My set of bits, the complete range from Ifixit when I got the set, only went down to Y0. Ifixit now has them. I got a Y00 at the same time to not have a gap.
Somewhere I have a few UMD disks, the DVD-esque media for the Sony Playstation Portable (PSP). At 64mm in diameter, it was smaller than the Minidisk (68mm) format, but it is still much larger than any of these.
