    • An apparatus includes a recording medium (100) having substrate (220) and markable coating (230). The apparatus also includes a recording/transmitting device including a light source (150) having at least two separate lasers, a unified apochromatic lens structure (148, 200, 300) having at least two separate lenses functioning as one structure, and a light separating means (201, 301). Lens structure (148, 200, 300) and light separating means (201, 301) enable light (152) to a) pass through lens structure (148, 200, 300) with at least two different wavelengths directed to at least two different spots on medium (100), so as to cause a localized change in chemical and/or physical properties to form at least two optically detectable marks (242) in markable coating (230), or b) pass through lens structure (148, 200, 300) with at least two different wavelengths directed to at least two different spots on medium (100), so as to cause at least one optically detectable mark (242) to reflect light (152). The light (152) has radiation different from a wavelength suitable for forming mark (242). ® KIPO & WIPO 2009
    • 一种装置包括具有衬底(220)和可标记涂层(230)的记录介质(100)。 该装置还包括一个记录/发送装置,它包括具有至少两个单独的激光器的光源(150),具有至少两个用作一个结构的分离透镜的均匀的复消色差透镜结构(148,200,300) (201,301)。 透镜结构(148,200,300)和光分离装置(201,301)使得光(152)能够以至少两个不同的波长穿过透镜结构(148,200,300),其指向至少两个不同的斑点 在介质(100)上,以引起化学和/或物理特性的局部变化,以在可标记涂层(230)中形成至少两个光学可检测标记(242),或b)通过透镜结构(148,200, 300),其具有指向介质(100)上的至少两个不同点的至少两个不同波长,以便使至少一个光学可检测标记(242)反射光(152)。 光(152)具有不同于适于形成标记(242)的波长的辐射。 ®KIPO&WIPO 2009
