ABSTRACT:
A transducer-to-medium stabilizer assembled with a transducer in a recording and/or reproducing apparatus is disposed in an opposing relationship with a flexible storage disk which is used as an information recording medium. The stabilizer comprises first and second block members which protrude from a base block member and a static pressure releasing arrangement on said stabilizer device. When the flexible storage disk is rotated at a high speed with respect to the stabilizer device, a negative pressure is formed between the stabilizer device and the disk, resulting in that the transducer is maintained in a constant and stable contact relationship with the disk.
