2. Magnetic storage - Wikipedia

   en.wikipedia.org/wiki/Magnetic_storage

   Magnetic storage or magnetic recording is the storage of data on a magnetized medium. Magnetic storage uses different patterns of magnetisation in a magnetizable material to store data and is a form of non-volatile memory. The information is accessed using one or more read/write heads.

3. Disk read-and-write head - Wikipedia

   en.wikipedia.org/wiki/Disk_read-and-write_head

   The functional part of the head is the round, orange structure in the middle. Also note the connection wires bonded to gold-plated pads. Read–write head of a 3 TB hard disk drive manufactured in 2013. The dark rectangular component is the slider and is 1.25 mm long. The platter surface moves past the head from right to left.

4. Bernoulli Box - Wikipedia

   en.wikipedia.org/wiki/Bernoulli_Box

   The original Bernoulli Box "Alpha-10" is a 10 MB removable disk drive that spins a disk made of PET film at about 1500 rpm, [1] 1 μm above a read-write head.Utilizing Bernoulli's principle, the rotation of the disk pulls the flexible disk media down towards the read/write head, and will continue to do so for as long as the disk is spinning.

5. Perpendicular recording - Wikipedia

   en.wikipedia.org/wiki/Perpendicular_recording

   This underlayer can be thought of as part of the write head, completing a magnetic circuit which transects the data storage layer. Having more of the magnetic flux penetrate the data storage layer makes the write head more efficient than a longitudinal head, produces a stronger write field gradient, and thereby allows the use of the higher ...

6. Hard disk drive - Wikipedia

   en.wikipedia.org/wiki/Hard_disk_drive

   Head stack with an actuator coil on the left and read/write heads on the right Close-up of a single read–write head, showing the side facing the platter The actuator is a permanent magnet and moving coil motor that swings the heads to the desired position.

7. Two-dimensional magnetic recording - Wikipedia

   en.wikipedia.org/wiki/Two-dimensional_magnetic...

   In an HDD, data is stored using magnetic recording on a rotating magnetic disk and is accessed through a write-head and read-head (or read-element). TDMR allows greater storage capacity by advantageously combining signals simultaneously from multiple read-back heads to enhance the recovery of one or more data-tracks.
