Optical disks rely totally on the ability of the pickup to follow and focus on the data track. It is taken for granted that these mechanisms are phenomenally accurate, work at high speed despite being made at low cost and need no maintenance.
The optical disk has some useful characteristics that have allowed it to survive alongside magnetic media. John Watkinson takes a look.
Magewell has upgraded its Ultra Stream HDMI standalone streaming encoder with browser-based remote control and optional mobile broadband support.
The hard disk drive rapidly converged on the concept of one head per surface with all of the heads moving together on a common positioner.
Digital sub-channels have allowed TV stations to utilize their allotted spectrum to create ways that also generate revenue. Cobalt Digital is working with major station groups and content originators to help them grow their channel ambitions with its line of signal processors.
We call them hard disks to distinguish them from floppy disks. As the latter have practically died out as a result of progress in solid-state storage such as flash memory, it is probably not necessary to specify that disks are hard anymore, but tradition is a powerful thing.
