Abstract

Un ensamble de unidad de disco de conformidad con la presente invencion, comprende: un disco con una sola superficie de registro que tiene una region substancialmente plana en su centro; un medio para hacer girar el disco; una unidad actuadora que incluye una sola suspension que soporta a un transductor; y un medio para "estacionar" el transductor en la region central del disco. En una modalidad preferida, el disco se monta directamente en un motor plano. En una modalidad alternativa, un cubo de motor o una estructura estacionaria que proporcionan en el centro del disco y están a nivel con el plano de la superficie de registro. El diseño de la presente invencion ofrece la ventaja de una unidad de disco de muy bajo perfil, particularmente adecuada para aplicaciones tales como unidades de disco de tipo de tarjeta.
