“…The amplitude rolls off at the same rate for all four media since they have the same effective spacing d + a = 18 nm. The BB-SNR is independent of the saturation magnetization (1) and (2). Its increase for media 2, 3, and 4 relative to media 1 is explained by the reduction of particle size (2): the media made of the smallest core-shell nanoparticles produce the expected 1.4 and 2.9 dB BB-SNR improvement associated with the particle volume reductions from 523 to 381 nm 3 and 268 nm 3 , respectively.…”

“…P ARTICULATE medium remains the main technology used in magnetic tape recording due to its good performance and cost advantage over alternative technologies, such as metal evaporated tape media [1] or sputtered tape media [2], [3]. A density of 29.5 Gb/in 2 has been demonstrated experimentally using perpendicularly oriented barium ferrite nanoparticles that have an average volume of 1600 nm 3 [4].…”

“…Existem pesquisas na utilização de nanocompósitos no campo de gravação de dados de alta densidade, onde o mesmo é descrito como a próxima geração de gravadores magnéticos. Por exemplo, um filme magnético com 5 nm de espessura pode armazenar cerca de 10 10 bit/cm 2 , sendo que, a princípio, seria possível utilizar diversas ferritas no processo de fabricação de um dispositivo para armazenamento de dados(MAI;YU, 2006;MATSUNUMA et al, 2012). Mistura dos percursores com os monômeros seguida de reações simultâneas de precipitação e polimerização. A precipitação das nanopartículas magnéticas e polimerização do monômero de forma separada, seguida com a dispersão das partículas na matriz polimérica;Esses quatro processos tendem a formar um determinado tipo de NCM.…”
