Abstract

Un sistema que incluye un dispositivo anfitrión y una unidad de disco interconectada con el dispositivo anfitrión se describen así como un método asociado. La unidad de disco incluye un medio magnético para almacenar información usando un arreglo de accionador para realizar un acceso a la información al mover al menos una cabeza próxima al medio magnético. La información puede estar sujeta a corrupción cuando la unidad de disco está expuesto, durante el durante el acceso a la información, a un campo magnético de dispersión dado que tiene un mínimo de intensidad de campo magnético. El campo magnético de dispersión dado no corromperá la información en el medio magnético con el arreglo de accionador colocado lejos del medio magnético. Un arreglo de protección contra un campo magnético de dispersión se configura para detectar un ambiente magnético para causar que el arreglo de accionador se estacione en respuesta a la detección de al menos un mínimo dado de intensidad de campo magnético.
