The prior art discloses a double-sided imprint lithography system (publication number CN101377618A), including a medium support unit, a support unit, wherein both surfaces of the medium are coated with UV curing resin; a first mold support unit and a second mold support unit, which respectively support the first mold and the second mold, and are respectively arranged above and below the medium support unit; a vertical movement device, which makes at least one of the medium support unit, the first mold support unit and the second support unit move vertically; a first UV irradiation device, which is installed above the first mold support unit to irradiate UV light; a second UV irradiation device, which is installed below the second mold support unit to irradiate UV light. When the above scheme is applied to the manufacture of patterned media for HDD, it can reduce manufacturing costs and improve productivity.

[0003] However, the above solution has the following defects:

[0004] First, the UV curing resin is coated on the upper and lower surfaces of the medium respectively. Considering the uniformity of the UV curing resin coating, it is easy to cause the flatness of the upper and lower surfaces of the medium to be poor.

[0005] Second, due to the size of the first mold and the second mold, it can only be used for small-format media, for example, media within 100 mm;

[0006] Third, when using, the ultraviolet (UV) curing resin needs to be melted first, and then cured after melting, which has a low operation speed and leads to low processing efficiency;
