Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method and apparatus for printing a magnetic disk medium coated with a magnetic recording material, and more specifically to a magnetic disk medium that can be manufactured at low cost and of good quality. The present invention relates to a media burning processing method and its apparatus.

Magnetic disk media coated with magnetic recording material can be subjected to a baking process to increase the strength and smoothness of the medium, or to reduce the adsorption force of the head. Generally, the disk disk is hung on a horizontal hanger for processing, but in the case of thermal radiation baking, in which the disk surface is exposed to radiant heat, if the distance between the heater and the heater is wide, the upper part will become hot, and if the distance is narrow, The middle part becomes high temperature, which causes baking unevenness in the baked medium in the circumferential direction. In other words, some parts of the media are burnt properly, while others are burned inappropriately, resulting in variations in the strength, smoothness, adsorption force of the head, etc. of the media. As a result, there were problems in that it caused uneven processing during media processing and failure during mounting.

The present invention has been made in view of the above-mentioned problems, and its purpose is to provide a method and apparatus for printing a magnetic disk medium, which can eliminate printing unevenness, provide good quality, and reduce manufacturing costs. It is about providing.

The above object is to: (1) support a plurality of disks coated with magnetic recording material and the plurality of disks in a row in the same plane; a transfer mechanism for transferring the disks, a rotation mechanism for rotating each disk on the transfer mechanism, and a rotation mechanism provided on both sides of the transfer mechanism and having a size such that at least the entire surface of the disk is exposed to heat rays. , and a heater that is elongated in the transfer direction, and performs a baking process on the plurality of disks by transferring the plurality of disks between the heaters while rotating the disks. (2) Burning of a magnetic disk medium, characterized in that a plurality of disks coated with magnetic recording material are rotated and transferred between heaters to perform a baking process. A processing method for a magnetic disk medium in which the disk rotates on its own axis in conjunction with the transfer of the disk using the force that transfers the disk, or (3) a magnetic recording material is coated. a hanger that supports the inner diameter of the disc; a transfer mechanism to which the hanger is rotatably attached and which transports the disc in the same direction as the surface of the disc; a plurality of pins provided on the periphery of the hanger; A heater is provided on both sides of the transfer route of the transfer mechanism and exposes the entire surface of the disk to hot rays; a fixing member that rotates the hanger in contact with the hanger; rotating the hanger causes the disk to rotate; and transferring the disk between the heaters while rotating the disk; (4) A cylindrical disk coated with a magnetic recording material is penetrated through the central circular hole, the disk is supported on the cylindrical surface, and one of the disks is A hanger in which a plurality of pins are embedded in the end face at intervals along the periphery of the end face, and a transfer unit that supports the hanger rotatably around its cylindrical axis and transports the hanger in one direction within the plane of the disc. a mechanism, a heater that sandwiches the disk to be transferred with a gap therebetween and exposes it to hot rays; a plurality of fixing members that protrude more protrudingly; the fixing members have a length that reaches at least one of the pins during transfer and does not reach the line of the trajectory drawn by the cylindrical axis of the hanger during transfer; has a width that allows it to fit between the pins,
As the hanger is transferred, the first fixing member engages with the pin of the hanger to rotate the hanger, and then the adjacent fixing member engages with another pin rotated by the transfer to rotate the hanger. rotate in the same direction,
This is accomplished by a magnetic disk medium burning processing apparatus that rotates the disc by sequentially engaging the corresponding pins and fixing members.

In addition, in items (2), (3), and (4) above, instead of providing separate drive sources for the transfer mechanism and rotation mechanism,
The disk is rotated using the transfer force of the transfer mechanism, and the drive source is only required on the transfer mechanism side.

An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a perspective view illustrating the configuration of a magnetic disk medium burning processing apparatus according to the present invention. In the figure, 7 is a furnace body that forms a nearly sealed internal space and has vertical slit-shaped openings at both ends in the horizontal direction. Far-infrared heaters 2 facing each other are arranged between both openings along a plane including the plane, and are arranged on both sides of the plane to form a heater row. In addition, a part of the conveyor 4 passes through the lower part of the internal space of the furnace body 7 along the plane.
Support shafts 6 are installed on the conveyor 4 at regular intervals. A disk-shaped hanger 3 is supported at the upper end of each of these support shafts 6 so as to be rotatable about a horizontal axis 5, and a plurality of pins projecting in a direction perpendicular to the surface of the hanger 3 are attached to the circumference of the hanger 3. installed on top. A plurality of fixing rods 11, 12, 13 fixed to the furnace body 7 are disposed so as to be engageable on the locus along which the pins 8, 9, 10 pass as the conveyor 4 moves. Note that 2 is a disc held in such a position that the inner peripheral part of the central hole is in contact with the hanger 3, and the conveyor 4 is driven in the direction shown by an arrow 14 by a drive source (not shown).

Since the main baking processing apparatus is constructed as described above, the disc 2 can be processed as follows. That is, the disk disk 2 coated with a magnetic material before the baking process is hung on the hanger 3, and is moved by the conveyor 4 through the far-infrared heater array at a constant speed that is optimal for baking.

Then, as shown in FIGS. 2 and 3, the hanger 3 automatically rotates due to the engagement of the tips of the fixing rods 11, 12, 13 with the pins 8, 9, 10, so that the disk circle hung on the hanger 3 The plate 2 also rotates as the conveyor 4 moves.

As described above, according to the present invention, the disk disk 2 is automatically rotated while passing through the baking furnace 7, and therefore, the entire circumference is evenly baked, resulting in a disk disk of good quality without baking unevenness. In addition, by using a far-infrared heater, heat absorption and curing are fast, and the conveyor allows continuous and efficient processing, which saves energy and lowers manufacturing costs. is extremely large.
