    1. Permasalahan : Menghitung Panjang Pita, Lama Akses, dan Transfer Rate pada Pita Magnetik dengan inputan Jumlah Record, panjang Record, IRG, IBG, Blocking Factor, Data Dencity, dan Laju Pita
    2. Algoritma :
      • Pertama menginputkan data
      • Memilih metode yang akan digunakan
      • Validasi inputan berdasar metode yang digunakan
      • Memproses inputan tersebut
      • Menampilkan hasil atau output
    3. Source Code
