The result is that overwriting data requires rewriting the entire set of closely-spaced tracks; that is an expensive tradeoff, but the benefitmuch higher storage densityis deemed to be worth the cost in some situations.
Some high-performance HDDs were manufactured with one head per track (e.g.

Enterprise HDDs can have sector sizes larger than 512 bytes (often 520, 524, 528 or 536 bytes).
Modern interfaces connect an HDD to a host bus interface adapter (today typically integrated into the " south bridge with one data/control forgotten administrator password windows server 2008 r2 cable.Enterprise drives (Parallel scsi/SAS/FC) support 520/528 byte 'fat' sectors.Market segments edit Desktop HDDs They typically store between 60 GB and 4 TB and rotate at 5,400 to 10,000 rpm, and have a media transfer rate.5 Gbit/s or higher (1 GB 109 bytes; 1 Gbit/s 109 bit/s).64 Areal density is the inverse of bit cell size, so an increase in areal density corresponds to a decrease in bit cell size."SFF-8500 Specification for Suite.25" Form Factor Specifications" (PDF)."5th Non-Volatile Memories Workshop (nvmw 2014 (PDF)."IBM Archives: IBM 1301 disk storage unit".Warns of mechanical issues but not other issues affecting reliability, and is therefore not a reliable indicator of condition.A b John.
