Magnetic storage recording medium and magnetic recording and playback device

A magnetic recording and playback device comprising:

• a magneto-resistive head;
• and
• a pair of reel supports for supporting a pair of reels of a magnetic storage medium loaded in the magnetic recording and playback device,
• wherein the reel supports are provided with an antistatic treatment.

A head drum for reading and writing information from and to a magnetic tape, the head drum comprising:

• a conductive rotating drum at the ground potential, the magnetic tape being wound in a helical manner around the rotating drum;
• a metal base fixed inside the rotating drum and electrically connected to the rotating drum;
• and
• a magnetic head fixed to the metal base, the magnetic head comprising:
• a head substrate and a protection substrate, both having a resistance of 1×1010 Ω or less and electrically connected to the metal base;
• a pair of outer insulating films disposed between the head substrate and the protection substrate;
• and
• a pair of magnetic shielding films disposed between the pair of outer insulating films;
• a pair of inner insulating films disposed between the pair of magnetic shielding films;
• and
• a magneto-resistive head element, disposed between the pair of inner insulating films, for reading stored signals by contacting the magnetic tape.
