Separate Read/Write heads are required in which of these memory access schemes.
Separate Read/Write heads are required in which of these memory access schemes.
The correct option is D None of these
Separate
Read/Write heads are required in None of these memory access schemes.
A
read/write head is a specific physical part of a hard disk that is responsible
for reading data from, and writing data to, the disk. Read/write heads are
typically made up of a thin horizontal magnetic blade attached to an actuator
arm. By changing the electrical polarity of bits on a magnetic disk, the
read/write arm effectively records data to a disk drive.
The read/write head reads
from and writes to a round hard disk platter that is housed in the physical
drive container. Unlike the disk platter, the actual read/write head is
extremely small. In modern disks these parts are designed down to the
nanoscale. Simpler read/write heads were eventually replaced with metal-in-gap
(MIG) heads, and then by thin-film heads that use different manufacturing
processes to create smaller equipment.
Disk read/write heads are the
small parts of a disk drive which move above the disk platter and transform the
platter's magnetic field into electrical current (read the disk) or, vice
versa, transform electrical current into magnetic field (write the disk).[1]
The heads have gone through a number of changes over the years.
