joy than a RAID 5 array of Seagate’s new 1.5 TB SATA drives. However, 500 GB of capacity is still impressive, as is the $85 price tag on the company’s Barracuda 7200.11 model. Based on second-generation perpendicular magnetic recording technology, Seagate’s...

Seagate, the first 3.5" hard disks to incorporate perpendicular magnetic recording (PMR) technology. PMR basically turns the magnetic domains on their sides so they stick down deeper into the magnetic substrate deposited on drive platter surfaces. Though this...

marketspace, introducing to it the concepts of Perpendicular Magnetic Recording (PMR) and improved shock tolerance ratings, to resist loss of data and incidental damage due to clumsy handling. Traditionally, data is stored on magnetic platters in a longitudinal...

vector. Without going into too much detail, light is an electromagnetic wave. Its electric and magnetic field vectors are perpendicular to the direction of its movement. A lamp emits non-polarized light, so the electrical field can travel in any direction perpendicular...
