Claim:
1. A system for providing reduced head-media spacing (HMS) in a hard disk drive (HDD), the system comprising: a disk having a magnetic data recording and reading surface; a read/write head including a magnetic transducer configured to read data from or write data to the magnetic surface of the disk; a z-axis actuator rigidly coupled to the read/write head and configured to control movement of the read/write head in a substantially orthogonal direction relative to the surface of the disk; a planar actuator rigidly coupled to the z-axis actuator and fixed in the orthogonal direction relative to the surface of the disk; and a servo controller in electrical communication with the z-axis actuator and configured to monitor a distance of the magnetic transducer relative to the disk surface, the servo controller configured to maintain the distance within a set range of head-media spacing (HMS) values.
