Abstract
A recording medium urging pad can urge a recording medium such as a magnetic tape against a recording and reproducing head stably and reliably. A head pad (10) fixed to a supporting member such as a leaf spring (9) comprises a first layer (10a) with a low elastic modulus contacting with a magnetic tape (T) and a second layer (10b) with an elastic modulus higher than that of the first layer (10a) fixed to the leaf spring (9), wherein a thickness (Ta) of the first layer (10a) and a thickness (Tb) of the second layer satisfy the following equation expressed as: ##EQU1## and the first and second layers (10a) and (10b) are bonded by an adhesive (10c).
