記憶用のレーザー光線３を照射されると照射された部分
だけ磁性が反転し再度属目の再生用のレーザー光線７を
照射されると磁性の反転した部分は再生用のレーザー光
線７に対して振動面が変化した反射レーザー光１１が反
射される。The storage surface 1 has a magnetic film on its surface, and when it is irradiated with a laser beam 3 for storage from a laser beam device 4, the magnetism is reversed only in the irradiated area, and when it is irradiated again with a laser beam 7 for reproducing the genus, the magnetism is reversed. A reflected laser beam 11 whose vibration plane has changed with respect to the laser beam 7 for reproduction is reflected at the portion where the laser beam 7 is formed.

ーザー光線３を走査制御回路５及びパターン記憶回路６
により制御する事により記憶面１の上に起こる磁性の変
化部分を記憶パターン２の様に作り出す事が出来る。For these reasons, the memory laser beam 3 emitted from the laser beam device 4 is transmitted to the scanning control circuit 5 and the pattern storage circuit 6.
By controlling this, it is possible to create a magnetically changing portion on the memory surface 1 like the memory pattern 2.
更にレーザー光線装置４より出る再生用のレーザー光７
を走査制御回路５にて記憶面１に対して水平及び垂直に
走査させる。Furthermore, a laser beam 7 for reproduction is emitted from the laser beam device 4.
The scanning control circuit 5 causes the storage surface 1 to be scanned horizontally and vertically.

となる。From this, the reflected laser beam 11 is reflected from the memory surface 1 whose magnetism has been changed as in the memory pattern 2 as described above, and only the portion where the vibration surface has changed becomes the transmitted laser beam 12 that passes through the filter 8 and is reproduced on the screen 9. pattern 10
becomes.
