Service-based inter-radio access technology (inter-RAT) handover
In geographical areas with incomplete Time Division Synchronous Code Division Multiple Access (TD-SCDMA) coverage, it may be beneficial for a multimode User Equipment (UE) to handover to a GSM network, a WCDMA network, a CDMA 1x RTT network, or an LTE network.

In another example, when a packet-switched call, such as a data call, is in progress on the UE, an inter-RAT handover to a WCDMA network occurs. Selecting a network for inter-RAT handover based on an active call service type improves the service provided to the UE. |

Transducer head temperature monitoring
Changes in the thermal boundary condition near a close point of an ABS to a media indicate proximity of the ABS with the media. Before contact, heat conduction from the ABS is primarily through convective and/or ballistic heat transfer to air between the ABS and the media.

Further, a light source within a HAMR transducer head may create additional thermal variations within the transducer head. These thermal variations create temperature variations within the transducer head. Two resistance temperature sensors on the transducer head at varying distances from the close point and/or light source measure these temperature variations. A temperature difference between the two resistance temperature sensors indicates proximity of the close point to the media and/or light output. |
