Abstract

DC60 (29/11/44) Magnetic transfer of information signals, such as servo signals, from a master carry to a slave medium is prevented from degrading due to imperfect contact between the master carry and the slave medium, which can lead to dust accumulation. Specifically, when the master carry containing the information signal is brought into close contact with the slave medium for magnetic transfer by applying a magnetic field, the slave medium with its vertically oriented recording surface is conveyed to the master carry, which is held in place by contact, with its information-containing surface also oriented vertically. The master carry and the slave medium are then brought into close contact, and magnetic transfer occurs via their defined contact surfaces. The vertical alignment of the contact surfaces prevents the accumulation of dust or similar particles. Magnetic transfer of information signals, such as servo signals, from the master carrier to the slave medium is prevented from degrading due to imperfect contact between the master and slave medium, which can lead to dust accumulation. Specifically, when the master carrier containing the information signals is brought into close contact with the slave medium for magnetic transfer by applying a magnetic field, the slave medium with its vertically oriented recording surface is conveyed to the master carrier, which is held in place by contact, with its information-containing surface also oriented vertically. The master carrier and slave medium are then brought into close contact, and magnetic transfer occurs, with their contact surfaces arranged vertically to prevent the accumulation of dust or similar particles.

Claims (9)

1. Magnetic Transfer Method: This method involves bringing a master receiver containing the information signals and a slave medium into close contact. A magnetic field is then emitted for transfer. The slave medium is transported with its surface oriented vertically towards the master receiver, which is held in a vertical position. The master receiver's information surface and the slave medium's recording surface are then brought into close contact. 2. Magnetic Transfer Method: This method involves bringing the master receiver containing the transfer information and the slave medium into close contact. A magnetic field is then applied, transporting the slave medium to a specific location for continued close contact with the master receiver. The slave medium is then held in place by a slave medium holder. 3. Magnetic transfer method as per claim 2, whereby the slave medium is positioned and held in the slave medium holder, and the alignment of the master receiver with the slave medium is performed using the slave medium holder. 4. Magnetic transfer devices perform magnetic transfer by bringing a master bearer containing the information signal and a slave medium into close contact. A magnetic field is then emitted for transfer. Such magnetic transfer devices consist of: a contact path that holds the master bearer so that its information-containing surface is oriented vertically and in contact with the slave medium; a conveying path that transports the slave medium so that its recording surface is oriented vertically toward the contact path; and a magnetic field generation path that emits a magnetic field to act on the slave medium and the master bearer held together by the contact path. 5. Magnetic transfer devices perform magnetic transfer by bringing a master carrier containing the information signals and a slave medium into close contact. A magnetic field is then released for transfer. Such magnetic transfer devices consist of: a base in close contact to position and hold the master carrier; a slave medium holder to position and hold the slave medium and transport it to the close contact position; a force application path to bring the held slave medium and the master carrier into close contact; a positioning mechanism to align the base in close contact with the slave medium holder; and a magnetic field release path to act on the slave medium and the master carrier in close contact. 6. Magnetic transfer device pursuant to claim 5 where more than one positioning pin or more than one positioning hole is provided on a closely contacting base; more than one positioning hole or more than one positioning pin is provided on such slave media holder; and the positioning mechanism aligns by inserting the positioning pins into the positioning holes. 7. Magnetic transfer device according to claim 6, where the diameter of the positioning hole is designed to be larger than the diameter of the positioning pin, and the positioning pin and positioning hole are partially fitted together to align them. 8. Magnetic recording medium in which information signals are magnetically transferred to the magnetic recording medium by the method described in Claim 1, consisting of servo signals. 9. Magnetic recording medium in which information signals are magnetically transferred to the magnetic recording medium by the method described in claim 4, consisting of servo signals.
