How does anti-skate work?
Anti-skate on a record player is there to counteract a natural inward pull on the tonearm as the record spins.
When a record rotates, friction between the stylus (needle) and the groove creates a force that pulls the tonearm toward the center of the record.
Types of Anti-Skate
Dial-based anti-skate (spring system)
How it works:
- Turning the dial increases tension on a small internal spring
- The spring pulls the tonearm outward to counter skating force
Pros:
- Quick and easy to adjust (just turn a dial)
- Clean, no external parts
- Good for everyday use
Cons:
- Spring tension isn’t perfectly linear
- Can vary slightly across the record (outer vs inner grooves)
- Calibration numbers on the dial are approximate, not exact
Weight-based anti-skate (hanging weight)
How it works:
- A small weight on a string hangs off the tonearm assembly
- Gravity provides a consistent outward pull
- You adjust force by moving the string to different notches
Pros:
- Very consistent force (gravity doesn’t change)
- More accurate and predictable
- Often better across the entire record surface
Cons:
- Exposed parts (can be bumped or moved accidentally)
- Less convenient for quick adjustments
