- Oct 7, 2026 Seek Time, Rotational Latency, and Why the Average Is Not the Middle How a drive decomposes an access into seek, settle, and rotation, why the mean seek is not half the maximum, and how queueing turns latency into a throughput number. hardware engineering
- Apr 25, 2026 Writing and Reading a Magnetic Bit on a Spinning Platter How a write head sets the direction of magnetisation in a granular medium, why transitions rather than levels carry the data, and what the read sensor and channel must recover. hardware engineering
- Apr 15, 2024 Shingled Magnetic Recording and the Write Cursor Why overlapping written tracks raise areal density, how that turns every random write into a band rewrite, and what a zoned interface has to expose to make the constraint usable. hardware engineering
