Abstract
PURPOSE: To obtain the best value of a low resonance frequency in pickup reproduction by realize a lightweight head shell of rigidity by using a composite material of a flake of AlB2 and matrix resin.
CONSTITUTION: A composite material, prepreg of a flake AlB2 and matrix resin made of thermosetting resin such as epoxy, polyester and polyimide, is used to form a head shell for fitting a cartidge. Since the obtained head shell is lightweight and large in rigidity, a low-band resonance frequency in pickup reproduction can be set to the best value of about 10W15Hz.
