Abstract: A smart wristwatch structure includes a glass, a dial, a watch case, a bottom case, a movement, an antenna, a functional module, and a dedicated battery. The dial, the watch case, and the bottom case construct an accommodating space from top to bottom. The antenna is adhered to a lower surface of the glass. The functional module is disposed in the accommodating space for wirelessly communicating with a mobile terminal. The dedicated battery provides power for the functional module or the movement. In the smart wristwatch structure, signals are not shielded, and the thickness of the watch case is not increased significantly.

Abstract: The present invention provides a wristwatch structure with physical hands and a method for offering a communication function to a wristwatch, which uses remaining room in a traditional wristwatch (such as a mechanical watch and a quartz watch) to dispose an electronic module. By way of wireless transmission, the electronic module is utilized to receive wireless signals transmitted from a device (such as a smart phone) near a wristwatch user, and to provide a prompt message (such as vibration or an audio sound) based on the wireless signals. The present invention gives a new function to the traditional wristwatch, and is also capable of solving the problem of prompt function not working in large-scale cell phone.

Abstract: An optical disc of a thicker supporting section and a thinner recording section is characterized by: a reinforcement section of a predetermined width which overlaps a supporting section and a recording section. With the reinforcement section, the structure of the optical disc is strengthened, and the resonant frequency of the optical disc is raised, so that the vibration of the optical disc is suppressed and the disc is suitable for high speed (16× up) reading/writing. The optical disc comprises: a circular opening disposed in the center of the optical disc; an annular recording section; an annular supporting section disposed between the annular recording section and the circular opening, wherein the annular supporting section is thicker than the annular recording section; and an annular reinforcement section which is disposed on one of the two sides of the optical disc and overlaps the annular supporting section and the annular recording section.

Abstract: A method of manufacturing an optical disc comprises the steps of: (1) forming a substrate including an inner supporting section and an outer information recording section, the inner supporting section having a thickness larger than that of the outer information recording section; and (2) forming a vibration suppressing layer by printing UV curable paste three to five times over the surface of the non-recording side of the outer information recording section from an inner edge of the outer information recording section to a designated diameter, wherein the printed UV curable paste has a weight of 15% to 25% of the weight of the substrate, and at least 90% of the weight of the printed UV curable paste is distributed within a circular region with diameter 90 mm to 110 mm, each time the UV curable paste printed not exceeding 5% of the weight of the substrate.

Abstract: An optical disc includes a round opening at the center of the optical disc, an annular recording section configured to record information, an annular supporting section between the round opening and the annular recording section and configured to support the optical disc, and a spoiler provided on a non-read/write side of the annular recording section and configured to disturb the flow field inside the optical disc drive when the optical disc is rotating, the spoiler having a centerline average roughness between 2 ?m and 10 ?m, a thickness between 0.02 mm and 0.05 mm, an area occupying at least 5% of the non-read/write side. The flow field so disturbed changes from a laminar state to a turbulent state and thus the read/write characteristics of the disc is improved due to lower air resistance experienced by the rotating disc.

Abstract: An optical disc includes an annular substrate, a coating layer, a damping layer, and a leveling layer. The annular substrate includes a supporting portion, and a recording portion surrounding the supporting portion, wherein the recording portion has a recording surface located on a first side thereof. For disc clamping and cost saving, the supporting portion is thicker than the recording portion. The coating layer is formed on the recoding surface for recording dada. The damping layer is formed on the coating layer to shorten the response time of the optical disc to vibration. The leveling layer is formed on the side of the annular substrate opposite to the recording surface for leveling the disk deformation caused during fabrication. A method for fabricating the aforementioned optical disc is also disclosed.

Abstract: The invention relates to a tool for coating an optical disc, and the tool includes: a coating section for spreading coating material; a restricting section for defining a coating area; and a support section for supporting the coating section and the restricting section. The coating section and the restricting section form a material accommodating space. Also, a method for coating an optical disc by using such tool and a method for fabricating an optical disc are disclosed.
