14.113 Hard Disks, Sectors, Zone Bit Recording, Sectors vs Blocks, CHS, LBA, Sparing

Описание: My book "Patterns in Data Management" is now available both as an ebook or a print book (with color graphics!). See: http://amzn.to/1Ts3rwx This book is not a standard textbook on database techniques. This book was written extending and complementing preexisting educational videos (including this one).

Why would hard disks still be important these days? What is a platter? What is a diskhead and a disk arm? How do tracks and cylinders relate? What is the difference of a circular sector from a HD sector? What is zone bit recording? What does this imply for sequential access? Where are self-correcting blocks used? What is the difference of HD sectors and operating systems blocks? What is physical cylinder/head/sector-addressing? What is logical cylinder/head/sector-addressing? How does it relate to the former? What is logical block addressing? What is sparing? What does this imply for sequential accesses?
