Enhanced low profile magnet write head

A magnetic read/write head comprising:

• an inductive write head having a pole tip located between an air bearing surface (ABS) and an apex of a second insulation layer, and a yoke located between the apex and a back gap, wherein the back gap is a location recessed from the ABS where first and second pole pieces are magnetically connected, comprising:
• first and second pole piece layers, the second pole piece layer having a pole tip and a yoke, the pole tip extending from an ABS end, which is located at said ABS, to a recessed end which is located at the apex, and the yoke extending from the apex, which is spaced from the ABS, to said back gap;
• a first insulation layer of non-magnetic inorganic dielectric material extending from a recessed end, which is recessed from the apex away from the ABS, to the back gap;
• a write gap layer sandwiched between the first pole piece layer and the first insulation layer, said write gap layer extending from the ABS to the back gap;
• a coil layer formed on the first insulation layer;
• and
• a second insulation layer sandwiched between the first insulation layer and the yoke of the second pole piece and overlaying the coil layer, the said second insulation layer extending from the apex, which is recessed from the ABS, to the back gap, said second insulation layer having a sloped surface forming an apex angle at the apex;
• a read head including:
• a magnetoresistive sensor;
• first and second gap layers;
• first and second shield layers;
• the magnetoresistive sensor being sandwiched between the first and second gap layers and the first and second gap layers being sandwiched between the first and second shield layers;
• and an insulation layer disposed between the second shield layer of the read head and the first first pole piece layer of the write head.

A disk drive system comprising:

• a magnetic recording disk;
• a magnetic read/write head for magnetically recording data on the magnetic recording disk and for sensing magnetically recorded data on the magnetic recording disk, said magnetic read/write head comprising:
• an inductive write head having a pole tip located between an air bearing surface (ABS) and an apex of a second insulation layer, and a yoke located between the apex and a back gap, wherein the back gap is a location recessed from the ABS where first and second pole pieces are magnetically connected, comprising:
• first and second pole piece layers, the second pole piece layer having a pole tip and a yoke, the pole tip extending from an ABS end, which is located at said ABS, to a recessed end which is located at the apex, and the yoke extending from the apex, which is spaced from the ABS, to said back gap;
• a first insulation layer of non-magnetic inorganic dielectric material extending from a recessed end, which is recessed from the apex away from the ABS, to the back gap;
• a write gap layer sandwiched between the first pole piece layer and the first insulation layer, said write gap layer extending from the ABS to the back gap;
• a coil layer formed on the first insulation layer;
• and
• a second insulation layer sandwiched between the first insulation layer and the yoke of the second pole piece and overlaying the coil layer, the said second insulation layer extending from the apex, which is recessed from the ABS, to the back gap, said second insulation layer having a sloped surface forming an apex angle at the apex;
• a read head including:
• a magnetoresistive sensor;
• first and second gap layers;
• first and second shield layers;
• the magnetoresistive sensor being sandwiched between the first and second gap layers and the first and second gap layers being sandwiched between the first and second shield layers;
• and
• an insulation layer disposed between the second shield layer of the read head and the first first pole piece layer of the write head;
• an actuator for moving said magnetic read/write head across the magnetic disk so that the read/write head may access different regions of the magnetic recording disk;
• and
• a recording channel coupled electrically to the write head for magnetically recording data on the magnetic recording disk and to the SV sensor of the read head for detecting changes in resistance of the SV sensor caused by rotation of the magnetization axis of the free ferromagnetic layer relative to the fixed magnetization of the AP-pinned layer in response to magnetic fields from the magnetically recorded data.
