Magneto-optical recording and reproducing devices have an electromagnet which reverses the magnetization of the magneto-optical layer of the magneto-optical disk in function of the bits to be stored.
Magneto-optical recording and reproducing equipment contains an electromagnet which reverses the magnetization of the magneto-optical layer of the magneto-optical disk in function of the bits to be stored.
Magneto-optical devices for recording and reproducing comprise an electromagnet which reverses the magnetization of the magneto-optical layer of the magneto-optical disk in function of the bits to be stored.
New data can be recorded without erasing the data already recorded on an optical disk such as a magneto-optical disk.
A magneto-optical data storage system (100) having a magneto-optical disk (107) rotatably mounted on a support body (108).
A magneto-optic disk drive (50) includes a magneto-optic disk (20) and a rotaty arm (52) for positioning a focus/bias field switching assembly (84) adjacent bit positions on the disk.
Magneto-optic recording and playing equipment uses an electromagnet to enable the magnetic field of the magneto-optic film on the magneto-optic disk to be reversed as a function of the bits to be stored.
First to third grooves (Gv1, Gv2, Gv3) are formed in a magneto-optical disc.
A magnetic head lifting device of a magneto-optical recorder and/or reproducer which uses a disc cartridge in which a magneto-optical disc is housed.
The invention relates to a carrier card suitable for carrying an optically readable disc such as a CD, a CD-ROM, a magneto-optical disc, a Mini-disc or a DVD or any other kind of known or future optically readable disc.
In more detail, data on the magneto-optical disc (2) is erased, and data is written on the magneto-optical disc (2), and the original data is checked with the written data.
Parallel p-polarized light is applied to a magneto-optical disc (1) and reflected.
An optical pickup device for reading data signals recorded in an optical recording medium such as a magnetooptical disk.
The compressed image data thus generated is stored in the temporary area of an magnetooptic disc (42).
A failure to record due to a defective magnetooptic disk (44) will display a message on a monitor (28).
Typically, the system includes RAM and/or a storage medium such as a digital audio tape, a magneto-optical mini-disk, a magnetic disk or optical disk, sufficient to store information for 10 hours of audio.
