O limite de densidade linear de gravação é definido para analisar o processo de gravação magnética em unidades de disco rígido de computador em densidades de gravação extremamente altas. Os dados digitais com sequências pseudo-aleatórias são registrados numericamente em meios longitudinais em diferentes densidades por um modelo de simulação micromagnético. Um cabeçote de gravação de filme fino e um cabeçote de leitura GMR ideal são utilizados no processo de gravação e leitura, respectivamente. Um novo método foi utilizado para estudar o limite de densidade linear de gravação: a tensão de leitura simulada e os pulsos lineares sobrepostos respeitados são comparados para encontrar a distorção no processo de gravação. Quando aparece uma distorção severa, a densidade linear correspondente é considerada como o limite de densidade linear de gravação. Pelo novo método, o limite de densidade linear de gravação é analisado com diferentes parâmetros da mídia de gravação.

Abstract: Write linear density limit is defined to analyze the magnetic recording process in computer hard disk drives at extremely high recording densities. The digital data with pseudo random sequences are recorded numerically in longitudinal media at different densities by a micromagnetic simulation model. A thin film write head and an ideal GMR read head are utilized in the record and read-back process, respectively. A novel method has been utilized to study the write linear density limit: the simulated read back voltage and the respected linear superposed pulses are compared to find the distortion in the record process. When a severe distortion shows up, the corresponding linear density is considered as the write linear density limit. By the novel method, the write linear density limit is analyzed with different parameters of the recording media.
