Patent number: 9956787Abstract: According to one embodiment, a laser recording device performs recording by irradiating a recording medium with laser light. The recording medium includes thermal recording layers including thermal materials with different color development threshold temperatures and stacked in an ascending order of the threshold temperatures of the included thermal materials from a surface irradiated with the laser light; and an intermediate layer provided between the thermal recording layers to perform thermal insulation and thermal conduction. The laser recording device includes a controller. The controller sets a power density of the laser light and an irradiation time and performs recording on the thermal recording layers by controlling irradiation with the laser light. The power density is relatively higher at recording of any of the thermal recording layers with a higher threshold temperature.Type: GrantFiled: March 7, 2016Date of Patent: May 1, 2018Assignee: Kabushiki Kaisha ToshibaInventors: Nobuki Nemoto, Fumitoshi Morimoto, Takahisa Nakano, Shota Kure, Takashi Yamaguchi
