Tascam Portastudios were factory-calibrated for Type II (high-bias/chrome) cassettes, and since they run at double speed recording all 4 tracks in one pass, tape choice has a real, audible effect on noise floor and headroom.

TASCAM MASTER 424 Studio Cassette
TASCAM’s own limited-release high-bias cobalt cassette, engineered specifically for Portastudio recording.
- High bias cobalt oxide formulation
- Rated ~4dB louder output than standard Type II tape
- Purpose-built for 4-track multitrack use
- Designed and voiced specifically for Portastudios
- Lower distortion, more headroom than generic tapes
- Limited release, can be harder to find
Maxell XLII-S High Bias Cassette
A widely favored Type II tape among Portastudio users for its clean, punchy sound.
- Type II high-bias formulation
- Low noise floor for its era
- C-60 length recommended for best base film thickness
- Long track record with 4-track recordists
- Good balance of clarity and warmth
- Discontinued — only available used/new-old-stock
TDK SA / SA-X High Bias Cassette
One of the most commonly recommended Type II tapes for 4-track Portastudio work.
- Type II high-bias formulation
- Consistent, well-regarded frequency response
- Widely used reference tape in the lo-fi recording community
- Reliable, well-documented performance on Portastudios
- Relatively easy to find used

BASF Chrome Plus Cassette
A true chrome-formulation Type II tape, an alternative to the TDK/Maxell options for the same high-bias performance.
- True chrome dioxide formulation
- Type II bias, factory-matched to Portastudio EQ

- Lower hiss than ferric (Type I) tapes
- Solid alternative if TDK/Maxell aren’t available

Buying tips
- Always use Type II (high bias/chrome) tapes — Portastudios are EQ-calibrated for them, and Type I tapes will sound noticeably worse.
- C-60 tapes are generally preferred over longer C-90s for their thicker base film and better durability under repeated multitrack passes.
- Since a Portastudio runs at double speed across all 4 tracks, a 60-minute tape only gives about 15 minutes of usable recording time — budget accordingly.
