Abstract
The main object of the present invention is to provide a substrate for storage media capable of recording and reproducing data for a limited period and capable of being easily recycled, and a method for manufacturing a recycled resin substrate reusable as such a substrate for storage media. In order to achieve the aforementioned object, the present invention provides a substrate for storage media comprising: a resin substrate containing a starch resin; and a resin layer formed on the resin substrate.
Claims9
1-9. (canceled)
A substrate for storage media comprising:
- a resin substrate containing a starch resin;
- and a resin layer formed on the resin substrate,
- wherein, after being left for a predetermined time, a compound having a carbonyl group is precipitated on a surface of the resin substrate.
(canceled)
A substrate for optical disk comprising:
- a resin substrate containing a starch resin;
- and a resin layer, formed on the resin substrate, having a recording pit or a recording guide groove on the surface,
- wherein, after being left for a predetermined time, a compound having a carbonyl group is precipitated on a surface of the resin substrate.
A method for manufacturing a recycled resin substrate, the method comprising a peeling step, in which the recycled resin substrate is formed, by peeling off a recording layer and a resin layer of storage media comprising a resin substrate containing a starch resin, the resin layer formed on the resin substrate, and the recording layer formed on the resin layer.
