Finite-size scaling is utilized to study the erasure mechanism in heat-assisted magnetic recording (HAMR). Predicted scaling equations are evaluated both numerically and experimentally by using the write current-assist percentage (WCAP) method. The m

The areal density achievable with heat-assisted magnetic recording (HAMR) is directly related to the temperature gradient produced in the recording media by the near-field transducer. The thermal gradient in the down track direction affects the linea

A method for measuring the magnetic field strength of the magnetic writer used in heat-assisted magnetic recording (HAMR) is presented. The measurement, termed write current assist percentage (WCAP), compares the laser current needed to erase a narro

Here we report the first series of in-plane thorium(IV), uranium(IV), and neptunium(IV) expanded porphyrin complexes. These actinide (An) complexes were synthesized using a hexa-aza porphyrin analogue, termed dipyriamethyrin, and the nonaqueous An(IV

In an ideal magnetic recording system, individual bits would be recorded as rectangular magnetic domains in the recording media, but in reality, the transitions from one bit to the next are curved due to practical geometry considerations. This is par

Differences between heat-assisted magnetic recording (HAMR) and conventional perpendicular magnetic recording (PMR) for signal processing of the written track by one and two reader multisensor magnetic recording (MSMR) are explored using spinstand me

The edge gradient of the thermal spot used to define bits in heat-assisted magnetic recording is a critical parameter in determining the quality of the magnetic transitions. We review the laser current modulation method used to measure this parameter

BACKGROUND It is increasingly common for women in high-income countries to delay childbearing. We aimed to describe the context of pregnancy for first-time mothers of different ages and examine relationships among maternal age at first birth, mode of
