1. A magnetic recording head, comprising:
a main pole disposed at a media facing surface (MFS);
a trailing shield disposed over the main pole;
a hot seed layer disposed between the main pole and the trailing shield at the MFS, the hot seed layer being spaced from the trailing shield;
a magnetic layer disposed in contact with the hot seed layer and the trailing shield at the MFS;
a conductive layer disposed between the main pole and the hot seed layer at the MFS;
a first blocking layer comprising a portion disposed between the main pole and the conductive layer; and
a second blocking layer disposed at least partially between the hot seed layer and the trailing shield.
