โทนอาร์มเชิงเส้น Zero-Point

คุณสมบัติเด่น

• Tangential tracking geometry achieves 0.000° tracking error at every point across the record surface
• 400 mm monocrystalline sapphire rail provides the bearing surface — second only to diamond in hardness
• Optical edge-tracking servo samples at 1 kHz with 0.001 mm resolution to maintain tangential alignment
• Vacuum-deposited beryllium tube and headshell: the lightest rigid structure achievable with current materials science
• Anti-skate is not applicable — skating force is a geometric consequence of pivoted arms and does not exist here
