HEAT-ASSISTED MAGNETIC RECORDING DEVICE INCORPORATING LASER HEATER FOR IMPROVED LASER STABILITY

The invention provides a heat-assisted magnetic recording device incorporating a laser heater for improved laser stability. An apparatus comprises a slider configured to facilitate heat assisted magnetic recording and a submount affixed to the slider. A laser unit is affixed to the submount and comprises a laser operable in a non-lasing state and a lasing state. A heater is embedded in the laser unit or the submount. The heater is configured to generate preheat for heating the laser during the non-lasing state and to generate steering heat for heating the laser during the lasing state. 本申请提供了结合激光器加热器的用于改进的激光器稳定性的热辅助磁记录设备。装置包括配置成用于促进热辅助磁记录的滑块和附连到该滑块的基板。激光器单元被附连到基板并且包括能以非发射激光状态和发射激光状态操作的激光器。加热器被嵌入在激光器单元或基板中。加热器被配置成用于在非发射激光状态期间生成用于加热激光器的预热并且在发射激光状态期间生成用于加热激光器的操控热。
