Which Blank Cassette Tape Do You Need?
Type I - Normal Bias Cassette Tapes
The universal format - every cassette deck ever made supports Type I. Gamma ferric oxide formulation delivers warm, full-bodied sound with strong low-frequency performance. Ideal for voice recording, spoken word, mixtapes, and general-purpose use. Best for Walkman recording and casual use. Top brands: TDK D, Maxell UR, Sony HF, BASF Chrome Extra I, Fuji FR-I.
Type II - High Bias Cassette Tapes
The audiophile standard for music recording throughout the 1980s and 1990s. Chrome or cobalt-modified ferric oxide formulation delivers lower noise, extended high-frequency response, and wider dynamic range than Type I. Requires a deck with a High Bias (CrO₂ / Type II) selector position. Best for home studio recording, hi-fi music recording, and 4-track recording. Top brands: TDK SA, TDK SA-X, Maxell XLII, Maxell XLII-S, Sony UX-S, Sony UX-Pro, AXIA PS-IIs, AXIA GT-IIx, That's CD Master.
Type IV - Metal Cassette Tapes
The highest-performance cassette format ever standardized. Pure metal particle formulation delivers maximum headroom, the lowest noise floor, and the highest coercivity of any cassette type. Requires a deck with a Metal (Type IV) position. Used for audiophile hi-fi recording, professional mastering, and archival duplication. Top brands: TDK MA, TDK MA-R, TDK MA-XG, Maxell MX, Sony Metal Master, Sony Metal ES, AXIA K Metal, Denon HD8, Fuji FR Metal.
Use Cases
Blank Cassette Tapes for Recording Music
For recording music, Type II high bias is the standard choice - lower noise, better high-frequency response, and wider dynamic range than Type I. TDK SA, Maxell XLII, and Sony UX-Pro are the reference-level options. For the absolute highest fidelity, Type IV metal delivers the best headroom and lowest noise floor of any cassette format. Match the tape type to your deck's bias selector position.
Blank Cassette Tapes for 4-Track Recording
For Tascam Portastudio, Fostex, and similar 4-track recorders, Type II high bias is strongly recommended. The lower noise floor and extended frequency response compensate for the signal loss inherent in 4-track recording. TDK SA-X and Maxell XLII-S are the preferred choices for 4-track home studio use.
Blank Cassette Tapes for Mixtapes & Walkman
For making mixtapes or recording for Walkman playback, Type I normal bias is the most accessible and compatible option. Every Walkman and portable player supports Type I without any settings adjustment. TDK D and Maxell UR are the classic choices - reliable, consistent, and available in C-60 and C-90 lengths.
Condition Grades
NOS - New Old Stock Cassette Tapes
Factory sealed in original packaging. Never opened, never used. In identical condition to the day they were manufactured. NOS blank cassette tapes represent the best available condition for any vintage tape - this is what collectors and audiophiles seek. The majority of our inventory is NOS.
B-Stock
New and unplayed, with minor cosmetic imperfections on the shell or outer packaging only - shelf wear, light scuffs, or imperfect shrink wrap. Audio performance is identical to NOS. Priced 10–30% below NOS equivalent.
C-Stock
Pre-owned tapes individually inspected, bias-tested, and confirmed to record correctly before listing. Priced at approximately 50% of the NOS equivalent - the most affordable way to record on premium-formulation tape.
Japanese Cassette Tapes
A significant portion of our inventory is Japan-domestic stock - tapes manufactured exclusively for the Japanese market, never exported through official channels. Japanese market cassette tapes frequently represent the highest-performance variants within a manufacturer's lineup: tighter production tolerances, premium shell construction, and formulation refinements that preceded or exceeded export versions. What makes Japanese cassette tapes better? Stricter quality control, higher-grade magnetic particle selection, and mechanical precision in shell assembly. Brands like AXIA (Fuji's Japan-only sub-brand) and That's / Taiyo Yuden were never exported at all - only available through specialist importers like Ultra Ferric.
Are NOS Cassette Tapes Better Than New Ones?
Yes - for any high-performance formulation. The Type II and Type IV cassette tapes in our inventory were manufactured by companies like TDK, Maxell, Sony, and AXIA at the peak of their magnetic media engineering capability. No current manufacturer produces anything equivalent. A sealed TDK SA-X or Maxell XLII from the 1980s or 1990s is a genuinely superior recording medium to anything available new today. Stored correctly - away from heat, humidity, and magnetic fields - NOS tape retains full performance indefinitely.
Cassette Tape Brands
We carry every major blank cassette tape brand of the analog era: TDK, Maxell, Sony, AXIA, Fuji, BASF, Denon, Nakamichi, That's / Taiyo Yuden, Ampex, 3M / Scotch, Panasonic, JVC, Hitachi / Lo-D, SKC, Radio Shack / Realistic, Capitol, Daiso, PD Magnetics, RCA, and more. Over 25 brands, 900+ individual titles - one of the largest NOS cassette tape inventories online.
Can You Still Buy Blank Cassette Tapes?
Yes - but the window is narrowing. TDK, Maxell, Sony, and BASF all ceased blank cassette tape production by the mid-2000s. What remains is NOS stock from original factory and warehouse inventory. Once it sells through, it cannot be replaced. Budget-grade Type I tapes are still manufactured by generic suppliers, but the high-performance Type II and Type IV formulations that defined the analog recording era are no longer produced anywhere in the world.

Frequently Asked Questions
What is the best blank cassette tape for recording music?
For music recording on a deck with Type II capability: TDK SA, TDK SA-X, Maxell XLII, Maxell XLII-S, and Sony UX-Pro are the reference choices - widely regarded as the finest Type II tapes ever produced. For Type IV: TDK MA-R, TDK MA-XG, Maxell MX, and Sony Metal Master are the benchmark options. For Type I: TDK D and Maxell UR deliver reliable performance at accessible prices. The best blank cassette tape depends on your deck - always match the tape type to your deck's supported bias and EQ settings.
What is the best cassette tape for a 4-track recorder?
Type II high bias is the standard recommendation for 4-track recorders, including the Tascam Portastudio range. TDK SA-X and Maxell XLII-S are the preferred choices - their lower noise floor and extended high-frequency response compensate for the signal loss inherent in narrow-track recording. C-60 length is recommended over C-90 for 4-track use, as thinner tape in longer cassettes can cause transport issues.
What cassette tape should I use for making a mixtape?
Type I normal bias in C-60 or C-90 length is the classic choice for mixtapes - universally compatible, easy to record on, and available in lengths that match a standard playlist. TDK D90 and Maxell UR90 are the go-to options. If your deck supports Type II, a TDK SA90 or Maxell XLII90 will deliver noticeably better sound quality for music recording.
Are blank cassette tapes still made?
Not by any major manufacturer. TDK, Maxell, Sony, and BASF ceased blank cassette tape production by the mid-2000s. Some budget-grade Type I tapes are still produced by generic manufacturers, but high-performance Type II and Type IV formulations are no longer manufactured anywhere. All of Ultra Ferric's premium inventory is new old stock (NOS) from original production runs - sealed, vault-stored, and finite.
What is NOS cassette tape?
NOS stands for New Old Stock - merchandise manufactured and packaged for retail sale but never sold, remaining in original factory or warehouse storage. NOS blank cassette tapes are factory sealed, never opened, and in identical condition to the day they were produced. They are the highest-quality available form of any discontinued product.
What is the difference between Type I, Type II, and Type IV cassette tape?
Type I (normal bias) uses gamma ferric oxide and works with every cassette deck. Type II (high bias / chrome) uses chrome or cobalt-modified oxide, requires a CrO₂/Type II deck setting, and delivers lower noise and better high-frequency response. Type IV (metal) uses pure metal particles, requires a Metal deck setting, and delivers the highest headroom and lowest noise floor of any cassette format. Always match your tape type to your deck's supported settings - using Type II on a Type I-only deck will result in incorrect bias and degraded sound quality.
What tape bias should I use?
Use the bias setting that matches your tape type. Type I tapes require Normal Bias (120μs EQ). Type II tapes require High Bias (70μs EQ) - look for a CrO₂ or Type II position on your deck. Type IV tapes require Metal Bias (70μs EQ) - look for a Metal position. Never record Type II tape on a Type I-only deck. If your deck only has one position, use Type I tapes only.
