High-speed response to laser heating and cooling in thermo-magnetic writing on magneto-optical disk memory

Autor: Hideki Akasaka, Jun Saito, Kazutomo Miyata

Publikováno v: 1994 Topical Meeting on Optical Data Storage.

In order to use Magneto-Optical (MO) media for multi media applications, it is necessary to achieve higher density, higher data transfer rate and lower cost technologies than current MO media. MO recording is thermo- magnetic recording. MO recordings

High-Speed Response to Laser Heating and Cooling in Thermo-Magnetic Recording on Magneto-Optical Disk Memory

Autor: Kazutomo Miyata, Jun Saito, Hideki Akasaka

Publikováno v: Optical Data Storage.

The achievement of high-speed capability, a large memory capacity and low cost technology is the main theme for developing Magneto-Optical (MO) data storage devices. In order to achieve the high-speed capability, we have some means such as multiplyin

LIMDOW MEDIA WITH MAGNETO STATIC COUPLING MSR FUNCTION

Autor: Kazutomo Miyata, Tetsuo Hosokawa, Akio Okamuro

Publikováno v: Journal of the Magnetics Society of Japan. 22:S2_177-180

We have developed the large capacity Light Intensity Modulation Direct Over Write (LIMDOW) Magneto Optical (MO)media by adding the Magnetically induced Super Resolution (MSR) function to the conventional LIMDOW. We selected the magneto static couplin

Autor: Akito Sakemoto, Shinichi Kurita, Kazutomo Miyata, Tetsuo Hosokawa, Akio Okamuro, Noriyuki Ogihara, M. Hashimoto, I. Kimura, T. Niwa, T. Sugiyama

Publikováno v: Journal of the Magnetics Society of Japan. 22:S2_61-63

We have developed Light intensity Modulation Direct Over Write (LIMDOW) Magneto Optical (MO) media whose structure gives CNR higher by 2dB than the conventional LIMDOW. In addition, cross-write characteristic has been improved by tuning of magnetic l

THE MOST ROBUST CONTROL FACTOR VALUES FOR RECORDING WITH THERMAL INTERFERENCE UNIFORMING TECHNIQUE ON DIRECT OVERWRITE MAGNETO-OPTICAL DISK

Autor: Kenta Morita, Jun Saito, Shinichi Kurita, Kazutomo Miyata, Hideki Akasaka

Publikováno v: Journal of the Magnetics Society of Japan. 19:S1_371-374

We have attempted to obtain the parameters of the recording laser waveform by computer simulation. For the laser waveform, we have used seven kinds of control factors. For the fluctuation of the mark shapes, we have used three kinds of noise factors.

DIRECT OVERWRITE MAGNETO-OPTICAL DISK AND HIGH DATA DENSITY RECORDING

Autor: Hiroyuki Matsumoto, Kazutomo Miyata, Jun Saito, Hideki Akasaka, Tetsuo Hosokawa, Akio Okamuro

Publikováno v: Journal of the Magnetics Society of Japan. 17:S1_353-356

MO disks have the thermal response functions to laser heating. Those thermal response functions have finite, not zero, values of time constant (τ). Thermal interference between the heat which forms recording marks, accordingly, causes thermal build-
