Problems solved by technology

As a result, a problem arises such that the film thickness is non-uniform between the outer circumferential portion and the inner circumferential portion, and the recording characteristic is deteriorated.
However, the method as described above involves such a problem that the running cost is expensive.
For this reason, the maintenance cost for the respective

second embodiment

[0143] As shown in FIG. 19, the production system 10B comprises a molding machine 20 for producing the substrate 202, a cooling section 22, and a manufacturing section 600 for producing the optical disk D from the substrate 202 after the cooling treatment.

[0144] The substrate 202, which is produced by the molding machine 20, is transported to the cooling section 22 by the aid of a transport mechanism 602. The substrate 202, which is cooled by the cooling section 22, is stacked and stored on the stack pole 24 installed as a plurality of individuals for the stacking section 26 (stack pole rotary table).

[0145] The manufacturing section 600 comprises three process units 604, 606, 608. The first process unit 604 includes a dye application mechanism 48 for forming the dye recording layer 204 (see FIG. 13) on the substrate 202 by applying the dye solution onto the first principal surface of the substrate 202 followed by drying, an inspecting mechanism 62 for inspecting the presence or abs...

third embodiment

[0166] As shown in FIG. 20, a production system 10C according to the present invention comprises two molding machines 20A, 20B, two dye application mechanisms 48A, 48B, and one sputtering mechanism 88.

fourth embodiment

[0167] As shown in FIG. 21, a production system 10D according to the present invention comprises three molding machines 20A, 20B, 20C, four dye application mechanisms 48A, 48B, 48C, 48D, and one sputtering mechanism 88.

Abstract

Disclosed is a method for producing an information-recording medium comprising, on a substrate, a dye recording layer capable of recording information, the method comprising the step of drying the substrate formed with the dye recording layer by allowing clean air to flow while rotating the substrate at a high speed; wherein an intake for introducing the clean air is narrowed by arranging a lid having a circular opening at a central portion, at an opening disposed at an upper portion of an apparatus for rotating the substrate at the high speed.

Description

[0001] 1. Field of the Invention[0002] The present invention relates to an information-recording medium having, on a substrate, a recording layer capable of recording information, and a method for producing the same.[0003] 2. Description of the Related Art[0004] In general, the optical information-recording medium (optical disk) capable of recording information only once by using the laser beam includes, for example, write-once type CD (so-called CD-R) and DVD-R. Such an optical information-recording medium is advantageous in that a small amount of CD's can be commercially supplied to the market quickly at a convenient price as compared with the production of conventional CD (compact disk). The demand for such an optical information-recording medium is increasing in accordance with the recent popularization of personal computers or the like.[0005] The optical information-recording medium of the CD-R type has a representative structure comprising a recording layer composed of an orga...
